Question 1

Populations changing genetically over time in response to variation in their environments is termed ________.

Accepted Answer

The answer of Populations changing genetically over time in response...

Question 2

Even though ecologists would like to study isolated levels of the environment, that would be difficult since all levels are interconnected.

Accepted Answer

Ecologists recognize that all levels of the environment, from individual organisms to entire ecosystems, are interconnected and interact with one another. Therefore, it is difficult to completely isolate a single level for study without considering its relationships with other levels.

Question 3

Which U.S. law protects endangered species?
A) Convention on International Trade in Endangered Species
B) The Endangered Species Act
C) The Species Protection Act
D) The Protection and Care of Species Act

Accepted Answer

The Endangered Species Act is a U.S. law that was enacted in 1973 to protect endangered and threatened species from extinction. It provides for the conservation of ecosystems upon which threatened and endangered species of fish, wildlife, and plants depend, as well as the protection of these species themselves. The other options mentioned are not specific U.S. laws that protect endangered species.

Question 4

Critical habitat protection for endangered species brings together the studies of adaptations of species, community through geographic levels of ecology, and global ecology.

Accepted Answer

Critical habitat protection involves understanding the specific needs of endangered species, their interactions with other species and their habitat at the community level, as well as the larger ecosystem and global factors that affect their chances of survival. Therefore, it brings together studies at different levels of ecology.

Question 5

Which of the following statements below demonstrates the interactions between ecological areas and processes?
A) The smallest level, the biosphere, is where we can see exchanges of materials, energy, and organisms.
B) Landscape ecology, the largest level of organization, has all of the areas on Earth that support life.
C) Exchanges between ecosystems leads to the level of landscape ecology.
D) Geographic ecology includes the exchanges between ecosystems leading to the level of landscape ecology.

Accepted Answer

This statement (C) describes how exchanges between ecosystems lead to the larger scale organization of landscape ecology, demonstrating the interactions between ecological areas and processes. The other options describe different levels of organization within ecology, but do not directly demonstrate interactions between them.
