Which of these changes in the food web would cause a decrease in the population of bald eagles
bogdanovich [222]

The correct answer is C. A decrease in the population of sea ducks

Explanation:

Food webs are diagrams that represent the relationship of organisms in an ecosystem by showing feeding or predatory relationships. This means food webs show which organisms eats another organism. In the case of the food web presented, this shows bald eagles fed on sea ducks and large piscivorous fish, this implies for survival bald eagles need from these two organisms. In this context, a decrease in the population of sea ducks (option C) would cause a decrease in the population of eagles because fewer sea ducks imply less food for eagles, and therefore fewer resources to survive.

What type of organism would most likely be found in place of the question marks?​
ruslelena [56]

Answer:

Decomposers

Explanation:

The diagram in this question illustrates a food web, which is a series of interlinked food chains in an ecosystem. In a food chain as depicted in the image, the arrows point to the organism that feeds on another organism. For example, an arrow is pointing from Idaho fescue to an Elk meaning that the elk will feed on that plant.

Different trophic levels constituting organisms exists in the food web including; producers (plants), primary consumers, secondary consumers, tertiary consumers etc. However, as observed in the image, a general arrow carrying along all the organism is pointing towards the organism in the question mark. This organism is called DECOMPOSER.

A decomposer, usually a microorganism, is an organism that breaks down dead organisms and returns the nutrient to the soil for recycling. All organisms in the food web will eventually die and when they do, they'll be decomposed by a decomposer. This is why the arrow pointing towards the decomposers include all organisms.
