Producers play the role of making their own food and providing energy for other organisms in a food web. Therefore, the correct answer is:
They make their own food and provide energy for other organisms.
Question 1
A)
Answer the following questions based on page 3

have learned in this unit.

(1 point)
They consume other organisms for nutrients.
They make their own food and provide energy for other organisms.
They decompose dead material.

Question 2
A) Which of the following correctly describes the sequence of energy transfer in a food
web? (1 point)
Primary consumers → Producers → Secondary consumers → Tertiary consumers
Producers → Secondary consumers → Primary consumers → Tertiary consumers
Producers → Primary consumers → Secondary consumers → Tertiary consumers
Tertiary consumers → Secondary consumers → Primary consumers → Producers
A) Which of the following correctly describes the sequence of energy transfer in a food
web? (1 point)
Primary consumers → Producers → Secondary consumers → Tertiary consumers
Producers → Secondary consumers → Primary consumers → Tertiary consumers
Producers → Primary consumers → Secondary consumers → Tertiary consumers
Tertiary consumers → Secondary consumers → Primary consumers → Producers
The correct sequence of energy transfer in a food web is:
Producers → Primary consumers → Secondary consumers → Tertiary consumers.
Question 3
A) In a food web, which type of organism is likely to be both a secondary consumer and
a primary consumer? (1 point)
Producer
Herbivore
Omnivore
Carnivore
A) In a food web, which type of organism is likely to be both a secondary consumer and
a primary consumer? (1 point)
Producer
Herbivore
Omnivore
Carnivore
In a food web, the type of organism that is likely to be both a secondary consumer and a primary consumer is an:
Omnivore.
Omnivores eat both plants (making them primary consumers) and other animals (making them secondary consumers).
Question 4
A) How does the interconnection of food chains in a food web contribute to the stability
of an ecosystem? (1 point)
It ensures that only one species is responsible for each trophic level.
It allows multiple organisms to share the same food source, providing alternative food
options if one source is depleted.
It limits the number of organisms that can occupy each trophic level.
It increases competition among species, leading to a decrease in population sizes

The interconnection of food chains in a food web contributes to the stability of an ecosystem because:
It allows multiple organisms to share the same food source, providing alternative food options if one source is depleted.
This redundancy helps maintain balance and supports the resilience of the ecosystem.
Question 5
A) If a primary consumer population decreases significantly in a freshwater ecosystem,
what is the most likely immediate impact on the secondary consumers? (1 point)
They will increase in number due to less competition.
They will migrate to find new food sources.
They will decrease in number due to a lack of food.
They will switch to being primary consumers.
Question 6
A) Which of the following best explains why energy transfer in a food web is described
as a pyramid? (1 point)
Energy is lost at each trophic level, with less energy available to organisms higher up in
the pyramid.
There are more producers than consumers in an ecosystem.
Tertiary consumers receive the most energy in an ecosystem.
The shape of the pyramid represents the physical structure of ecosystems.

Energy is lost at each trophic level, with less energy available to organisms higher up in
the pyramid.
There are more producers than consumers in an ecosystem.
Tertiary consumers receive the most energy in an ecosystem.
The shape of the pyramid represents the physical structure of ecosystems.
Question 5:
If a primary consumer population decreases significantly in a freshwater ecosystem, the most likely immediate impact on the secondary consumers is:
They will decrease in number due to a lack of food.
Question 6:
The best explanation for why energy transfer in a food web is described as a pyramid is:
Energy is lost at each trophic level, with less energy available to organisms higher up in the pyramid.
This reflects the inefficiency of energy transfer through the food web.
