A Community Of Organisms With Their Environment

Each step in a food chain is a “trophic level” because of the energy transfer between them which can be shown in energy pyramids. All of the energy that passes on originally comes from the sun before moving through the order of the trophic levels, which is from producers to primary consumers to secondary consumers, then eventually to tertiary consumers. Although, as one lifeform eats another for energy, only 10% transfers to the next level because that 90% is used to “carry out the functions of living, such as producing new cells, regulating body temperature, and moving,” or for other necessary tasks. These transfers through eating are important since they help maintain ecosystems like the Everglades Hardwood Hammock. (Arms,

As defined by “Environmental Science- 14th Edition”, an ecosystem is “a set of organisms within a defined area or volume that interact with one another and with their environment of nonliving matter and energy.” I will be using the computer simulation to alter the interactions of the organisms in the ecosystem to see what changes occur.

Ecology is the branch of biology that studies the relationship between organisms and their environment. Ecology is a basic tool of environmental science.

An ecosystem is a community of interacting organisms and their environment. If one of the organisms is disturbed, it can change the trophic cascade which is a sequence of impacts down the food chain. Hannibal supports this statement by writing “keeping these connections going ensures healthy, functioning ecosystems, which in turn support human life.”(578) An example of this is if all of the beavers died the other organisms would go somewhere else or die due because they no longer will have dams to support their ideal habitat.

Ecosystem management takes an integrated view of terrestrial and aquatic ecosystems, integrates ecological concepts at a variety of spatial scales, incorporates the perspectives of landscape ecology so that the range of possible landscapes in an ecosystem is recognized and preserved, and is an evolving paradigm incorporating the objective of ecological sustainability.

Ecosystems is the dynamic complex of plant, animal and micro-organism communities and their non-living environment that work together to form a functional unit and they are constantly changing due to the fluctuating equilibrium from natural stress and human action which has had adversarial impacts on ecosystems. This is evident in Minnamurra rainforest as human induced modifications and environmental stresses had resulted in a vulnerable ecosystem. Furthermore, the removal of factors that contribute to the vulnerability of an ecosystem is important as it affect the functioning of the ecosystem as processes are accelerated, biodiversity is decreased which greatly affects humans. Despite the negative effects caused by humans, they have discovered that ecosystems are susceptible from harm caused by natural environmental factors or human impacts and realised the importance of protecting and managing ecosystems therefore have implemented management strategies that are supposed to prevent further detriment and as a consequence may induce resiliency.

Herbivores make up the second trophic level. Predators that eat herbivores comprise the third trophic level; if larger predators are present they are then represent a higher trophic level. Organisms that feed at several trophic levels are classified at the highest of trophic levels at which they feed. Decomposers breakdown wastes and dead organisms and return nutrients back to the soil. (Future Direction International,

Ecosystem: a system formed by the interaction of a community of organisms with their environment

-Ecosystem: any environment containing living organisms interacting with each other and with the non-living parts of that environment.

A population consists of all individuals of a species that occur together at a given place and time. All populations living together and the physical factors with which they interact compose an ecosystem.

In the ecosystem organisms rely on each other for food and protection. The Food chain is like a pyramid you have the producers, primary consumers, secondary consumers, tertiary consumers, and quaternary consumers. It’s an almost perfect balance and if any level were to just stop existing then the food chain would be destroyed. An example of organisms relying on others is an issue of isle royale were the wolves and moose population are in jeopardy. This relationship is important because without the other animal the population would die.

A biome, also known as life zones, consists of all plants, animals, and other organisms, as well the physical environment in a particular area. A biome is characterized by its’ plant life, climate, and location. The climate and physical features determine the boundaries of a biome. A biome is made up of many different ecosystems. The ecosystems tend to have the same pants and animals as neighboring biomes around the boundaries. The major biomes are the tundra, taiga, tropical rain forest, temperate forests, desert, grassland, savanna, chaparral, and marine. Each biome has it’s own characteristics such as the tundra.

Ecology today can be defined as “the study of the interrelationships between living things and their environment”. It is important to understand that when we say that ecology includes the “environment”, we are talking about everything that is external to an organism, all the biotic and abiotic. Nowadays it also attempts to understand and explain the how and why of the origins and mechanisms of interactions.

Biomes are all over the world, that’s why they are considered the “world’s major communities.” Biomes are large areas scattered around the earth, filled with animals and plants acclimating to their environments. You can classify biomes in many different ways, by their climate, their biodiversity, human activity, their animals and plants, and their habitats. There are only five conspicuous types of biomes, Grassland, Tundra, Desert, Aquatic, and forest. Without biomes, the earth would be unbalanced. Throughout the years, we have cause a lot of damage towards our earth, such as causing pollution, and abolishing natural habitats. If we continue living like this, there might be more serious or severe implications on the biomes. Knowing that we share the world with so many other species of plants and animals, we should consider the consequences of our actions.

Biodiversity presents occurrence of variety of species and their natural community in which they live. By the definition it is “The degree of variation of life forms within a given species, ecosystem, biome, or an entire planet. It is a measure of the health of ecosystems and is in part a function of climate.” (Rutherford) Ecosystem is on the other hand, “ community and its abiotic environment”( Rutherford). Biodiversity exists in every ecosystem, weather it is big one, or just ecosystem of one garden, it has the same importance because without it nature loses its ability to perform major functions needed for life on Earth, as it is oxygen production. Trough this investigation, two different ecosystems will be explored and
