Producers play the role of making their own food and providing energy for other organisms in a food web. This means they are essential for the flow of energy through the ecosystem, serving as the primary source of energy for consumers (herbivores, carnivores, and omnivores).
Answer the following questions based on page 3 (the Overview) and the information you have learned in this unit.

The type of organism that is likely to be both a secondary consumer and a primary consumer is an omnivore.
Responses
It ensures that only one species is responsible for each trophic level.
It ensures that only one species is responsible for each trophic level.
It allows multiple organisms to share the same food source, providing alternative food options if one source is depleted.
It allows multiple organisms to share the same food source, providing alternative food options if one source is depleted.
It limits the number of organisms that can occupy each trophic level.
It limits the number of organisms that can occupy each trophic level.
It increases competition among species, leading to a decrease in population sizes.
The correct response is:
It allows multiple organisms to share the same food source, providing alternative food options if one source is depleted.
This interconnection helps contribute to the stability of an ecosystem by allowing for flexibility and resilience in the face of changes or disruptions.
Responses
They will increase in number due to less competition.
They will increase in number due to less competition.
They will migrate to find new food sources.
They will migrate to find new food sources.
They will decrease in number due to a lack of food.
They will decrease in number due to a lack of food.
They will switch to being primary consumers.
The most likely immediate impact on the secondary consumers if a primary consumer population decreases significantly in a freshwater ecosystem is:
They will decrease in number due to a lack of food.
