Question 26 options:

primary consumers


ecosystem engineers


pioneer species


parasites

Question 27 (1 point)

Maintaining biodiversity is extremely important as it increases the stability of ecosystems.

Question 28 options:
True
False
Question 29 (1 point)
Question 29 options:
The ultimate goal of ecological succession is to create an ideal, stable environment known as a
. Although modern scientists believe that real ecosystems are disturbed too often to ever actual acheive this goal.
Question 30 (1 point)

Answer 1

Here are the answers to your questions:

**Question 22**: True
**Explanation**: An age pyramid is indeed a tool used to represent the age-sex structure of a population.

**Question 23**: True
**Explanation**: Ecological succession is the process by which the species composition of an ecosystem changes over time.

**Question 24**: False
**Explanation**: An ecosystem with greater species diversity is generally more resilient and less likely to collapse if one species is removed compared to an ecosystem with lesser diversity.

**Question 25**: Genetic diversity
**Explanation**: Genetic diversity refers to the variation in genetic characteristics within a single population, which helps in understanding how diverse the traits are in that population.

**Question 26**: Pioneer species
**Explanation**: Pioneer species are the first organisms to colonize a new ecosystem.

**Question 27**: True
**Explanation**: Lichens are effective pioneer species because they can break down bare rock and contribute to soil formation.

**Question 28**: True
**Explanation**: Maintaining biodiversity is important as it tends to increase the stability and resilience of ecosystems.

**Question 29**: Climax community
**Explanation**: The ultimate goal of ecological succession is to create a stable environment known as a climax community, although ecosystems may never fully achieve this due to disturbances.

**Question 30**: Both A and C
**Explanation**: Both forest fires and tornadoes are examples of disturbances that can lead to secondary succession.
