The Interactions and Interrelationships among the Different Components of the Ecosystem

I. Introduction

Ecology is the study of environmental systems, or as it is sometimes called, the economy of nature (Hall and Weiss, 2010). It studies interactions between different organisms and their environments, including relations within its own species and members of others. Ecology focuses more on the population, community, and ecosystem ecology although it also includes a wide variety of fields. Both the living (biotic) and the non-living (abiotic) components of the natural world is its subject matter. Processes like primary production, nutrient …show more content…

In addition, people who work in the field of agriculture will be affected.

In Tables 1.2 and 1.3, results show that these two ecosystems, the freshwater and forest have a more diverse number of both autotrophic and heterotrophic organisms than a manmade ecosystem. These environments are less manipulated by a person that is why there are a lot of different species of plants and animals living in these areas. With many nutrients and food dispersed in the area, there is a random distribution for most of the organisms here.

Physical factors of the environment that interact with the plants are light intensity, temperature, relative humidity, wind velocity and wave velocity. Plants rely on these factors for many functions like growth, germination, flowering, and photosynthetic activity. Plants also adapt to some changes in the physical environment. In a forest ecosystem, little light is received by plants in the forest floor so plants have broader and greener leaves for better absorption of light. In an agro-ecosystem however, plants like rice are distributed evenly so no competition is present for the absorption of light. Instead, their leaves are composed of hair-like structures or cuticles to retain more moisture against the intense light of the sun.

Temperature controls growth, flowering, germination, ripening of fruit and transpiration of plants. Since the plants listed from the
