1. The Namib-Naukluft National Park is located along the coast of Namibia. The park includes a desert ecosystem that gets most of its water from fog that blows in from the ocean.

Question

This dry environment is home to sidewinder snakes, hyenas, and beetles. The park is also home to welwitschia plants. These plants can live to be over 1000 years old.

Which term best describes the snakes, hyenas, beetles, and welwitschia plants in the national parks?

Answer 1

The term that best describes the snakes, hyenas, beetles, and welwitschia plants in the Namib-Naukluft National Park is a community.

A community refers to all the different populations of organisms (including plants and animals) living and interacting in a particular area. In this case, the snakes, hyenas, beetles, and welwitschia plants represent different populations that together form a community within the national park.

Answer 2

Cabo Pulmo National Park is a protected marine area off the coast of Mexico. The National Park includes salt water, rocks, and sandy beaches.

Under the water is a coral reef that is estimated to be 20,000 years old. The reef is home to many species of fish and sea snails. In addition, manta rays often visit the reef.

Which term best describes a group of manta rays in Cabo Pulmo National Park?

Answer 3

The term that best describes a group of manta rays in Cabo Pulmo National Park is a population.

A population refers to a group of individuals of the same species that live in a particular area. In this case, the group of manta rays would be considered a population within the marine ecosystem of Cabo Pulmo National Park.

Answer 4

Which statement about lemmings in a tundra ecosystem is most likely true? (1 point)
Responses

Lemmings interact with the biotic parts and abiotic parts in their environment to live and grow.
Lemmings interact with the biotic parts and abiotic parts in their environment to live and grow.

To stay safe, lemmings do not interact with the biotic parts of their tundra ecosystem.
To stay safe, lemmings do not interact with the biotic parts of their tundra ecosystem.

Lemmings live and grow by interacting with the biotic parts, but not with abiotic parts of their environment.

Answer 5

The statement that is most likely true about lemmings in a tundra ecosystem is:

Lemmings interact with the biotic parts and abiotic parts in their environment to live and grow.

Lemmings, like other organisms, depend on both biotic (living) components, such as plants and predators, and abiotic (non-living) components, such as soil, water, and temperature, to survive and thrive in their tundra ecosystem. The other statements are incorrect because they imply that lemmings do not interact with essential parts of their environment.

6. A community is comprised of only one species in a specific area. (1 point)
Responses

True
True

False

Answer 9

False

A community is comprised of multiple species in a specific area. It includes all the different populations of organisms that interact with one another in that environment. A single species would represent a population, not a community.
