2. what is the difference between consumers and producers?
3. how are primary consumers, tertiary consumers and secondary consumers related? to earn full credit, you
must explain how they interact with each other.
4. does the arrow point to the predator or the prey in a food web?
5. read the descriptions and identify each organism by their trophic level
shrew - a large wetland rodent that gets its energy from small insects.
snake - a carnivorous wetland reptile that gets its energy from eating rodents and frogs
marsh grass - a wetland grass that, like all plants, gets its energy from the sun. this plant provides energy for
insects in the wetland food web.
frog -- an amphibian hat mainly gets its energy from hunting insects
hawk - a top wetland predator which gets its energy from large wetland organisms such as snakes and shrews.
grasshopper - a wetland insect that gets its energy from plants
tertiary consumers
and higher
secondary consumers

2. Producers are autotrophs while the consumers are heterotrophs in nature.

3. The primary consumers are the herbivores who get food from the producers, primary consumers are eaten by secondary consumers, they are carnivores and eventually, secondary consumers obtain their nutrition from secondary consumers. Secondary consumers can eat both omnivores and carnivore as their energy source.

4. Arrow point is at the predator

prey⇒predator.

5 marsh grass (producer) is eaten by grasshopper (primary consumer), is  consumed by shrew or frog (secondary consumer) are eaten by snake (tertiary consumer) is eventually consumed by hawk (higher consumer k/a the axial consumers).

It is to be noted that hawk can consume both snake and frog. Also, frog can prey upon shrew.

Explanation:

2.Producers are green plants and some bacteria which can manufacture their food from sunlight, they are the one who initiates the food chain.

The heterotrophs get their nutrition from these plants and chain continues to be axial consumers.

3. In this hierarchy the energy is being transferred in the upward direction. The biomass is also segregated in the same hierarchy. This chain is necessary to maintain the stability of the ecosystem.
