 Feeding Relationships between Organisms

The Ecosystem

Ecology is the study of relationships between organisms and their environment. The living (biotic) environment includes all the living things that an organism interacts with; the physical (abiotic) environment includes the non-living aspects such as light, temperature and water. all these interacting factors in a specific area make up an ecosystem.

What is an Habitat?

There are many habitats within an ecosystem. A habitat is the place where organism lives. Organisms of the same species living in a particular habitat make up a population. The living organism in any ecosystem are made up of producers, consumers and decomposers.

Producers: Manufacture organic substances using water, carbon dioxide and energy from light or from chemical reactions.

Consumers: Are animals that eat other organisms to obtain energy and nutrients.

Types of Consumers:

Primary Consumers

• Herbivores: these are animals that only eat plant  

Secondary Consumers

• Carnivores: these are animals that eat other animals.

• Omnivore: these animals eats both plants and animals  

Tertiary Consumers

• these animals feed on secondary consumers.

Decomposers or Detritivores:   these are organisms that feed on dead organisms to obtain energy.
