Week 7 HW: Keystone, Food Web, Carrying Capacity, Cell Transport

Front

What is carrying capacity?

Back

The maximum number of individuals of a species that an environment can support sustainably.

Front

What is diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What are limiting factors?

Back

Environmental conditions that restrict population growth, such as food availability, predation, and disease.

Front

What happens to a cell in a hypotonic solution?

Back

Water moves into the cell, causing it to swell.

Front

What happens to a cell in a hypertonic solution?

Back

Water moves out of the cell, causing it to shrink.

Front

What is an isotonic solution?

Back

A solution where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

Why is diffusion important for cells?

Back

It allows cells to take in necessary materials without expending energy.

Front

What is the role of producers in a food web?

Back

Producers, like plants, convert sunlight into energy, forming the base of the food web.

Front

What is a consumer in a food web?

Back

An organism that obtains energy by consuming other organisms.
