Unit 3 Ecology (part 2)

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes such as evaporation, condensation, and precipitation.

Front

What is evaporation in the water cycle?

Back

Evaporation is the process by which water changes from a liquid to a gas (water vapor) due to heat.

Front

What is condensation in the water cycle?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is precipitation in the water cycle?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, including rain, snow, sleet, and hail.

Front

What is nitrogen fixation?

Back

Nitrogen fixation is the process by which nitrogen in the atmosphere is converted into ammonia or related compounds in soil, making it available for plants.

Front

Why can't plants and animals use nitrogen directly from the air?

Back

Plants and animals cannot use nitrogen directly from the air because it is in a gaseous form (N2) that is not chemically reactive.

Front

What factors can increase a population size?

Back

Factors that can increase a population size include a high birth rate and immigration.

Front

What is an invasive species?

Back

An invasive species is a non-native species that is introduced to a new environment and typically causes harm to the ecosystem.

Front

What is exponential growth in population dynamics?

Back

Exponential growth is a rapid increase in population size where the growth rate is proportional to the current population, leading to a J-shaped curve.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.
