What happens to an ecosystem when the primary consumers disappear?(1 point)
Responses
a. Both the producer and secondary consumer populations decrease.
b. The producer population increases, while the secondary consumer population decreases.
c. Both the producer and secondary consumer populations increase.
d. The producer population decreases, while the secondary consumer population increases.
Here are the answers
1: The wolves increased the population by eating a competitor.
2: The deer population increased.
3: willow
4: The producer population increases, while the secondary consumer population decreases.
If the primary consumers disappear from an ecosystem, the producer population will increase, while the secondary consumer population will decrease. Therefore, the correct answer is (b) The producer population increases, while the secondary consumer population decreases.
To answer this question, we need to understand the role of primary consumers in an ecosystem. Primary consumers are the organisms that directly consume producers (plants or algae) for food. They are usually herbivores, such as rabbits, deer, or insects.
When primary consumers disappear from an ecosystem, it has a cascading effect on the other populations within that ecosystem. Without primary consumers, the population of producers (plants or algae) will typically increase. This is because there are no longer as many organisms consuming them, allowing their populations to thrive.
On the other hand, the absence of primary consumers may cause a decrease in the population of secondary consumers, which are organisms that feed on the primary consumers. Secondary consumers are often carnivores, such as wolves or lions, which rely on the abundance of primary consumers for food. With the decrease in primary consumers, there may not be enough food available to support the same number of secondary consumers, resulting in a decrease in their population.
Based on this information, the correct answer to the question is:
b. The producer population increases, while the secondary consumer population decreases.
