Unit 1 Environmental science

Hydroelectric Power is electrical energy generated from the force of moving water. It is the most widely used type of renewable energy.

Fossil fuels are classified as nonrenewable because they take millions of years to replace.

The energy pyramid represents the distribution of energy among different trophic levels in an ecosystem, with less energy available at higher levels.

Natural Selection is the process where better-adapted organisms survive and pass their advantageous traits to their offspring.

Advantageous traits are more likely to be passed on because organisms with these traits are more likely to survive and reproduce.

A renewable energy source is an energy source that can be replenished naturally, such as solar, wind, and hydroelectric power.

Fossil fuels are natural substances formed from the remains of ancient plants and animals, including coal, oil, and natural gas.

Biodiversity is important for ecosystem stability, resilience, and the provision of ecosystem services.

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

The main types of renewable energy include solar energy, wind energy, hydroelectric power, geothermal energy, and biomass.
