Answer: Option B food web
Explanation:
- A conceptual model is the one which shows the interaction between the living and non living components of the ecosystem with the help of a flow chart.
- The conceptual models are also called as compartmental models.
- An example of the conceptual model present in the ecosystem is the food web.
- A food web is a system of interlocking food chains which shows the feeding relationship between various organisms.
- A food chain is simply a linear flow chart which shows who eats who in an ecosystem. e.g grass-----> insect----->vole---->hawk
- When several food chains are linked together we get a food web.
- The organisms in the food web are shown connected to each other with the help of arrows. These arrows are used to describe the feeding relation between the various organism and thus, the flow of energy.
- An example of a food web is attached along with the answer.
- All the other options that are given such as inheritance, infiltration and circulatory system do not show a conceptual model as they do not show a relationship between organisms in the ecosystem.
So, the food web is the conceptual model that represents flow of energy in an ecosystem.
