Question

Which principle states that two species in the same habitat cannot have the same niche?
niche exclusion principle
competitive exclusion principle
habitat exclusion principle
population exclusion principle

Answer 1

The principle that states that two species in the same habitat cannot have the same niche is known as the **competitive exclusion principle**. This principle asserts that if two species compete for the same resources, one will outcompete the other, leading to the exclusion of one species from that niche.

Answer 2

A rock is classified as%0D%0Anonliving and abiotic.%0D%0Anonliving and biotic.%0D%0Aliving and abiotic.%0D%0Aliving and biotic.

Answer 3

A rock is classified as **nonliving and abiotic**. Abiotic factors are nonliving components of the environment, such as rocks, water, and air, in contrast to biotic factors, which are living organisms.

Answer 4

Which best describes a bird’s role as it eats seeds?
parasite
predator
habitat
niche

Answer 5

The term that best describes a bird's role as it eats seeds is **niche**. A niche encompasses the role and position a species has in its environment, including how it obtains its food, interacts with other organisms, and contributes to the ecosystem. In this case, the bird's role in consuming seeds is part of its ecological niche.

Answer 6

Hunter is studying for his ecology test. Which fact would least likely show up in his notes?
Populations can have negative effects on their environment.
Populations can affect the size of other populations.
Populations have no effect on their environment.
Populations can adapt to changes in the environment.

Answer 7

The fact that would least likely show up in Hunter's notes is: **Populations have no effect on their environment.**

This statement is inaccurate because populations do have effects on their environment, whether through resource consumption, habitat alteration, or other ecological interactions. The other statements reflect true ecological concepts regarding the interactions and effects populations have on one another and their environments.

Answer 8

Which describes the habitat of a frog?
color for camouflage
prey for snakes
eats insects
marshes and ponds

Answer 9

The option that describes the habitat of a frog is **marshes and ponds**. A habitat refers to the natural environment in which an organism lives, and frogs are typically found in wetland areas such as marshes and ponds. The other options describe aspects of a frog's behavior or ecological relationships rather than its habitat.

Answer 10

Which is biotic?
soil
leaf
water
snow

Answer 11

The biotic option from the list is **leaf**. Biotic factors are living components of an ecosystem, while the others—soil, water, and snow—are abiotic factors, as they are nonliving components of the environment.
