Question 1

Secondary succession will start with bare ground that is lacking any type of soil.

Accepted Answer

Secondary succession occurs after an area has been partially or completely cleared but still has some remaining soil. Primary succession occurs on bare ground without any soil.

Question 2

There are two plowed fields that are each one acre and one mile apart with a wood surrounding one and the other surrounded by a pasture; they have the same soil composition and climate.In the first field,as succession begins,the pioneer species are pine trees and shrubs.In the second field,the pioneer species are weeds and shrubs.This provides evidence for which model of succession?

Accepted Answer

The fact that different pioneer species colonize each field suggests that the soil and climate are not the primary driving factors of succession. Instead, the tolerance model suggests that the initial conditions of the site determine which species can establish and thrive, as certain plants are better adapted to compete for resources in different environments. In this case, the first field may have had more resources available for woody plants like pine trees, while the second field may have had more resources for weedy plants.

Question 3

During mutualism,one species benefits while the other is harmed.

Accepted Answer

During mutualism, both species involved benefit from the interaction.

Question 4

At the basic level an ecologist will study how an organism is adapted to its environment.

Accepted Answer

This statement is true. The basic level of ecology is concerned with the study of how organisms are adapted to their environment.

Question 5

One model proposed for succession predicts that different types of plants can all colonize an area at the same time and it is chance alone that determines which one arrives first and begins the process of succession.This model is called

Accepted Answer

The answer of One model proposed for succession predicts that...

Question 6

The climax pattern model states that the same area will always lead to a specific type of community if it is given a sufficient amount of time.Which of the following statements is true of this model?

Accepted Answer

The statement that "In recent time this has been modified to recognize that while the area may return to the same biome it may not have exactly the same species diversity" is true of the climax pattern model. This recognizes that there are factors that can affect the species diversity of a climax community, such as climate change or human activity.
