Question

Create two food chain from the following list: •raccoon •mallard duck •mosquito larva •algae •Elodea •Freshwater clam •human •duckweed

Answer 1

Two examples of food chains from the given list are: 1) Algae -> Mosquito larva -> Mallard duck, and 2) Duckweed -> Freshwater clam -> Raccoon -> Human. Algae and duckweed act as producers, mosquito larva and freshwater clam as primary consumers, while mallard duck, raccoon, and human are secondary and tertiary consumers respectively.

Step-by-step explanation:

A food chain is an ecological model that shows how energy and nutrients flow through an ecosystem from one organism to another. In constructing two food chains from a given list, we take into account the roles of producers, consumers, and decomposers. Producers are organisms that can make their own food using light, water, carbon dioxide, or other chemicals. Consumers are organisms that cannot produce their own food and need to consume other organisms for energy.

Here are two examples of food chains from the provided list:

1. 
   
3. Algae (producer) -> Mosquito larva (primary consumer/herbivore) -> Mallard duck (secondary consumer/carnivore).
4. 
   
6. Duckweed (producer) -> Freshwater clam (primary consumer/herbivore) -> Raccoon (secondary consumer/omnivore) -> Human (tertiary consumer/omnivore).

In both of these food chains, algae and duckweed are examples of producers, as they create their own food and support the other organisms in the chain. Mosquito larva and freshwater clam are primary consumers that feed on the producers. These consumers are then eaten by secondary consumers, the mallard duck and the raccoon, while humans categorize as tertiary consumers in this context.
