(a) Define the term ecosystem. (b) Describe the main components of the ecosystem citing two examples of each. (c) Explain two ways in which the components of the ecosystem are interdependent.
(a) An ecosystem is a community of living organisms (plants, animals, and microorganisms) interacting with each other and their non-living environment (air, water, and soil).
(b) The main components of an ecosystem are:
Abiotic factors: These are the non-living components of the ecosystem, such as water, air, and soil. Examples of abiotic factors include rocks, sunlight, and temperature.
Biotic factors: These are the living components of the ecosystem, such as plants, animals, and microorganisms. Examples of biotic factors include trees, birds, and bacteria.
Examples of abiotic components:
Water: This is an important abiotic component of aquatic ecosystems, and it provides a habitat for fish, aquatic plants, and other organisms.
Soil: This is an important abiotic component of terrestrial ecosystems, and it provides a habitat for plants, insects, and microorganisms.
Examples of biotic components:
Plants: These are primary producers in most ecosystems, and they provide food and shelter for animals. Examples include grasses, trees, and algae.
Animals: These are consumers in the ecosystem, and they help to regulate populations of other organisms. Examples include insects, mammals, and birds.
(c) The components of an ecosystem are interdependent in many ways. Two examples are:
Nutrient cycling: Biotic components of the ecosystem, such as plants and microorganisms, require certain nutrients to survive. These nutrients are provided by abiotic components, such as soil and water. As biotic components consume these nutrients, they release waste products that are broken down by other biotic components and returned to the abiotic environment. This cycle of nutrient uptake, consumption, and recycling is essential for the survival of the ecosystem.
Predation: In many ecosystems, animals consume other animals as a source of food. This predation helps to regulate the populations of different species, preventing any one species from becoming too dominant. If the predator population declines, prey populations can grow unchecked, which can lead to overgrazing, habitat destruction, and other negative effects on the ecosystem. Therefore, the biotic components of the ecosystem are interdependent on each other for survival.
