The Four Approaches Of Ecology Study

Some plants and animals have to adapt to the amount of oxygen and visibility underwater. For example, plants have adapted to the amount of sunlight they receive in certain environments, and cattails and water lilies have adapted to be able to survive humid climates. For animals, certain fish like trout have adapted to clear and cool water with a large amount of oxygen. On the other hand, other types of fish, like catfish, are able to survive in an area with a low oxygen level and gloomy visibility. Since otters live on the land surrounding the water, they have adapted to be able to swim to catch their food. Frogs and alligators have adapted to their environment by being able to live on the land after coming from underwater as an egg. Lastly, beavers have adapted to use their teeth to create the dams they live

Introduction: Photosynthesis can be defined as a solar powered process that removes atmospheric carbon dioxide and transforms it into oxygen and carbohydrates (Harris-Haller 2014). Photosynthesis can be considered to be the most important biochemical process on Earth because it helps plants to grow its roots, leaves, and fruits, and plants serve as autotrophs which are crucial to the food chain on earth. Several factors determine the process of photosynthesis. Light is one these factors and is the main subject of this experiment. The intensity of light is a property of light that is important for photosynthesis to occur. Brighter light causes more light to touch the surface of the plant which increases the rate of photosynthesis (Speer 1997). This is why there is a tendency of higher rates of photosynthesis in climates with a lot of sunlight than areas that primarily do not get as much sunlight. Light wavelength is also a property of

The Ecological Theory is not being probed in this research; it is limited to be an organizing tool. The interview guide that we use tried to include all the systems in the theory (macro, micro, meso, exo, and crhono5), and their probable relations through different issues, which will correspond to one or more systems. However, even the theory would not define the study, it contributes to the design.

Aquatic environments require different methods for adaptation. The pressure in water increases as depth increases and aquatic organisms have to deal with it. Mobility of small animals versus larger ones help the ones with greater SA:V flow or be moved by currents, which is a disadvantage for bigger animals that have to constantly move. Light limitations also affect living things in water, mostly plants because they have to photosynthesize to grow, and the attenuation of light increases in depth, they have to take advantage of other resources to get the light they need and the nutrients to survive. Salt tolerance is vital; the process of osmosis moves water from high concentration of solutes to low concentration of solutes, if an organism doesn’t have enough salt contents starts losing water and dehydrates

There are several major trends that developed in the vertebrate group that has allowed the transition from aquatic to terrestrial life. Some of these trends are improved respiration, protective body covering, and more efficient ways to reproduce. The adaptations that have allowed the transition from aquatic to terrestrial life are: Jaws, lungs, jointed vertebrate limbs, water tight skin, amniotic egg for reproduction. In birds and mammals another adaptation that has evolved is that they are endothermic meaning they generate internal heat.

An important part of photosynthesis is the intake of carbon; thus, it can be presumed that increasing the amount of available carbon will increase photosynthetic activity. In most plants there is an increased rate of photosynthetic rate, but it is limited by other factors and reaches a plateau (Lei H, Zhishan Z.

Ecology is the branch of biology that studies the interactions of organisms with each other, and with their physical and chemical environments. Another main topic discussed in this chapter is ecosystems. Ecosystems are habitats or areas that consists of two basic components. Ecosystems include such things as biotic and abiotic components. Biotic components are living organisms within an ecosystem and abiotic components are things like sunlight, temperature, and rainfall. Within an ecosystem are producer and autotrophs. Producers and autotrophs consist of plants, algae, and bacteria. These two organisms obtain food from inorganic materials and light energy. As to where consumer and heterotrophs obtain energy by eating plants or the animals that eat the plants. An ecosystem is made up of several different parts. Each part of an ecosystem is different from the other. None of these parts within the ecosystem rely on the other. They are all interdependent being either predators or

My biome is the Taiga. One place the Taiga can be found is Oslo,Norway. Some abiotic factors in the Taiga are rain, sunlight, soil, temperature, and wind. Some biotic factors are moose, black bears, wolves, moss, and pine trees. Those abiotic and biotic factors interact a lot. There are four levels of organization. They are species, population, community, and ecosystem. An ecosystem is all the biotic and abiotic factors in a specific place. An example of a ecosystem in the Taiga is spruce trees, pine trees, mushrooms, owls, and bears. Those are only a few of the abiotic and biotic factors that make up the Taiga.

Angle Fish can live in a habittat that is either fresh water or salt water. An Angle Fish thats home is in salt water is called a marine Angle Fish, and other Angle Fish that live in fresh water are simply called Freshwater Angle Fish.And despite there small aperance, Angle Fish are very friendly to divers and will even

The process of osmoregulation is one important feature that all fish possess within their anatomy to main its salt and water levels balance with the environment that it is living in. The California Golden Trout is no exception. Since it is a freshwater fish, the Golden Trout’s body is more likely to have a higher level of salts compare to the environment that it is living in. Therefore, the chance of them losing salt and absorbing more water is inevitable. In order for them to maintain the balance of both water and salt levels, they would need an efficient kidney to push out the water as quick as possible as its body is more likely to absorb water from the environment. Furthermore, as their salt level drop, the Golden

Think of marine mammals, which breathe air like we do but drink only salt water. How do aquatic organisms deal with the different concentrations of salt in the water:

Interactions between populations within communities also lead to complex properties. As environmental conditions change in time and space, the structure of the community changes both physically and biologically, resulting in a mosaic in the landscape (variety or patterns ) in a community. Communities are comprised of different populations of organisms that interact with each other in either negative or positive ways (e.g., competition, parasitism and mutualism); community ecology seeks to understand the manner in which groupings of species are distributed in nature, and how they are influenced by their abiotic environment and species interactions. The physical structure of a community is affected by abiotic factors, such as the depth and flow of water in a stream, and also by the spatial distribution of organisms, such as in the canopy of trees. The mix of species in terms of both the number of individuals and the diversity of species defines the structure of the community. Mathematical or computer models can be used to illustrate and investigate

There's an adaptation for everything. Mammals, reptiles, and these deep-sea creatures as well. For some animals to live functionally in the environments in which they were placed, they develop some rather unusual traits and features to help them to survive in their habitat. The giant squid, zombie worms, large jellyfish and even the yeti crab serve as excellent examples of animals which developed certain adaptations to help them live in their extreme deep-sea environment.
