Guinea Grass And The Mango Tree

In this lab write up, the population growth of a variety of living organisms was analyzed and upon analysis of graphs and background information given within the laboratory course notebook, the conclusion was made that abiotic factors are related to biotic factors in an ecosystem, if one factor is varied it can affect the entirety of the ecosystem. Abiotic factors have importance because they are directly correlated to how biotic organisms survive and the growth or decline of their populations. Abiotic factors refer to non-living physical and chemical elements in the ecosystem and biotic factors are living or once-living organisms in the ecosystem with the ability to reproduce and affect other organisms in the ecosystem.

he canopy describes the dense foliage in the upper region of the layers of stratification within a rainforest environment. This feature of an ecosystems dictates determines the abiotic features for the plants below. The features key features of humidity, sunlight and wind strength is controlled by the canopy layer. The conditions created by the canopy commonly favours the survival of other large tree, as higher quality light, which is essential for the process of photosynthesis is found closer to the opening of the canopy. As seen in the first photo on the right, a gap in the canopy caused by the falling of a large tree has significant impacts on the function of the ecosystem. This disturbance causes the onset of the recycling of nutrients

An ecosystem is the dynamic complex of plant, animal and micro-organism communities and their non-living environment as a functional unit. Ecosystems are systems through which incoming solar energy is captured and channelled through a hierarchy of life forms. Each ecosystem has its own characteristic plant and animal community.

The abiotic factors present in this ecosystem consist of temperature, light, water, minerals, and air. Majority of organisms living in this aquatic environment require specific temperatures to survive, although temperatures can vary according to the species. Obviously, water is a part of the aquatic environment, and is actually essential to all parts of life. Light plays a major part in the photosynthesis process for many organisms

Adaptations in terrestrial environments involve the structural and functional qualities of the organism, to achieve the adequate intake of oxygen and other essential substances for the animal to survive, the evolution of more complex anatomical structures were required. Gravity is stronger on land than water, which means terrestrial organisms have to be more structural than aquatic organisms. Also, the balance of gas exchange with water loss is a key feature to survive in land. For example plants, when doing photosynthesis require carbon dioxide and water to produce oxygen, at the end of this process a lot of water is lost and terrestrial plants have to compensate the water being lost and the water taken from soil. Furthermore, the dispersal of gametes by wind or other animals have helped plants reproduce in large amounts and create varieties of species of the same kind. Short-term weather patterns as well as long-term climate conditions based on precipitations, temperature, wind, humidity as well as other factors are survival obstacles that organisms in land have to adapt to live; endothermic organisms have to maintain a constant internal

Plants are found everywhere on earth, up high on the ridge and down low in caves and caverns. The types of plants that live in these places depends on many factors. These factors are separated into two different categories, the biotic factors and the abiotic factors. Some of the biotic factors include, predation, competition, and habitat destruction. Plants with limited competition and large amounts of resources will be in a higher abundance than plants with limited resources and higher competition rates will be confined to areas and either out competed or will be the dominant species. Certain plants adapt to these factors and thrive and others don’t do as well. Some of the abiotic factors include, sunlight, water, temperature, and wind. These

In order for an ecosystem to stay an ecosystem there are three aspects that interact with each other:

Abiotic factors refer to non-living physical and chemical elements in the ecosystem. These factors have effects on living things and determine which species survive in a particular environment.

Most animals of the grasslands rely on the abundance of plant life around them. Animals such as bison, antelope, elephants, giraffes, zebras, and many others eat plants in the grasslands. These animals are often targeted by the hunter animals. You could group these animals as carnivores.

includes both biotic and abiotic components. A biotic constituent is a living organism needing to

Ecology has been the study of different interactions amongst organisms with the abiotic environment (Pimm and Smith, 2007), examining how ecosystems have thrived upon these relations. Ecosystems have depended on the continued availability of energy supplied ultimately by plants through the process of photosynthesis. Plants have lived in association with each other from having occupied the same niche in nature (Khan and Hussain, 1999). Numerous plants have

Ecosystems maintain themselves by recycling energy and nutrients obtained from external sources. At the first trophic level of primary producers i.e. plants and algae, use solar energy to produce organic plant material through photosynthesis.

Plant growth is dependent on environment factors and the activities of the meristematic tissues after germination (Dunlop et al, 2010). Some environmental factors that will affect plant growth are soil pH and external stimulus. Most plants can only grow well within a narrow range of pH values; 6-8 (Dunlop et al, 2010). Any soil that is more acidic or basic will result in poor or no plant growth. Phototropism is the growth response of a plant to light due to an unequal distribution of auxin (Dunlop et al, 2010; Tucker, 2006). This causes the plant to grow towards the light source and the cells on the side opposite to the light elongate. Dunlop & Tucker state that this results in the stem curving towards the direction of the light.The meristematic

enough sunlight for plants to live. In the Mesopelagic Zone, only small amounts of light

This also can help bind the soil together which helps conserve the soil by minimizing the soil erosion. Numerous organisms rely on vegetation as their primary source of shelter. Even green plants can moderate surface temperatures by making a natural cooling when the prevent the suns heating effect. Also, overall the aesthetic of the plant such as the flowers make the environment even more beautiful.
