Ecosystem Part 2 (General Principles in Ecology)

is a community of different living organisms in conjunction with the nonliving components of their environment, interacting as a system.

It is a collection of all organisms that live in a particular place together with their nonliving environment.

Ecosystem has two types:

Natural Ecosystem can take in several forms:

the living component of an ecosystem.

are the non-living component of an ecosystem.

Climatic Factors:

Edaphic Factors:

Biotic Components kinds:

Consumers (Heterotrophs) kinds:

Is the relative position of an entity in the food chain.

▪It forms the feeding positions in a food web or chain.

All food webs and chains have at least two or three trophic levels.

The Autotrophs Auto (means “________”) + trophḗ (aGreek word, meaning “_____”/“_______”/”_______”).

Members of this tropic level are capable of producing their own food source.

They acts as the food producers in a food chain.

Give some examples of autotrophs:

Hetero-(means “_______”) + trophe (aGreek word, meaning “________”/“_____”/”____”).

Organisms’ member of this tropic level depends on the producers for nourishment.

They acts as the consumers in a food chain.

Classification of heterotrophs based on diets:

Microorganisms, including detritivores, feed on decomposing materials to break down its components into simpler molecules.
