Question

what is a food web?
a model that shows specifically how energy moves through living things
an interaction where one organism kills and eats another organism
a one - way model that shows how food resources are exchanged between living things
a model that represents all the feeding relationships within a community of organisms

Explanation:

A food web is a complex model. It shows all the feeding relationships (who eats whom) among organisms in a community. It's not just about one - way energy flow (like a simple food chain) but a comprehensive representation of multiple interconnected feeding paths.

• The first option is more about a food chain (a simple linear model of energy flow).
• The second option describes predation (a single interaction).
• The third option is incorrect as it's not just about food resource exchange in a one - way simple sense.

Answer:

A model that represents all the feeding relationships within a community of organisms.
