LE Mid Term Review

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance. It involves a series of stages where different species colonize an area, leading to a stable ecosystem.

Front

What is renewable energy?

Back

Renewable energy is energy that is generated from natural resources that can be replenished, such as wind, solar, and hydroelectric power. It typically causes minimal damage to the atmosphere.

Front

What is the role of carbon dioxide in the environment?

Back

Carbon dioxide is a greenhouse gas that is essential for photosynthesis in plants. It is absorbed by plants and converted into oxygen, playing a crucial role in the carbon cycle.

Front

How does overfishing affect ocean ecosystems?

Back

Overfishing can lead to a decrease in fish populations, which disrupts the balance of marine ecosystems, decreases biodiversity, and can lead to a decrease in the stability of the oceans.

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms. Enzymes are specific to the substrates they act upon.

Front

What is the significance of wind power?

Back

Wind power is significant because it is a renewable energy source that can reduce reliance on fossil fuels and decrease greenhouse gas emissions.

Front

What are the main components of the carbon cycle?

Back

The main components of the carbon cycle include carbon dioxide, photosynthesis, respiration, decomposition, and combustion.

Front

What is the impact of deforestation on ecosystems?

Back

Deforestation leads to habitat loss, decreased biodiversity, and disruption of water cycles, which can result in climate change and soil erosion.

Front

What is the difference between renewable and non-renewable resources?

Back

Renewable resources can be replenished naturally over time (e.g., solar, wind), while non-renewable resources exist in finite amounts and cannot be replaced once used (e.g., fossil fuels).

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.
