Question

How would a population decrease in primary consumers affect the ecosystem?

Answer 1

A population decrease in primary producers would affect the ecosystem negatively because everyone who ate the primary consumers would have a lack of food.

Answer 2

If the population of primary consumers decrease, the population of the primary producers will increases excessively while the population of the secondary and tertiary consumers decreases.

An ecosystem is a self sustaining unit in which there is an exchange of materials and energy. In an ecosystem, energy flows from one trophic level to the other as organisms feed on each other.

A typical food chain include; Primary producers ----> primary consumers ----> Secondary consumers ----> Tertiary consumers ----> Decomposes. Hence, if the population of primary consumers decrease, the population of the primary producers will increases excessively while the population of the secondary and tertiary consumers decreases.
