What is the difference between a habitat and an ecosystem?

• A habitat is a type of ecosystem that includes only plants.

• A habitat is the specific environment where an organism lives, while an ecosystem includes all living and nonliving things in a particular area.

• A habitat refers to the climate of an area, while an ecosystem refers to the geography.

• A habitat is a larger area that encompasses multiple ecosystems.

What is the significance of the cell membrane?

• It provides structural support to the cell.

• It controls what enters and exits the cell, maintaining homeostasis.

• It stores genetic information for the cell.

• It produces energy for the cell.

What is natural selection?

• Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

• Natural selection is the method by which species are created through random mutations.

• Natural selection is the phenomenon where all organisms have an equal chance of survival regardless of their traits.

• Natural selection is the process of breeding organisms with desirable traits to enhance their survival.
