Unit 4 Ecosystem Review

Front

What are biotic factors in an ecosystem?

Back

Biotic factors are the living components of an ecosystem, including plants, animals, fungi, and microorganisms that interact with each other and their environment.

Front

How do scientists study biotic interactions?

Back

Scientists study biotic interactions by analyzing the relationships and interactions between living organisms, such as predation, competition, and symbiosis.

What is the fastest source of energy for the body?

Back

Sugars and starches are the fastest sources of energy for the body, as they are quickly converted into glucose.

Front

What is the primary function of food in growth and repair?

Back

The primary function of food in the body's growth and repair processes is to supply building materials for tissues and organs.

Front

What is ATP and its role in cellular activities?

Back

ATP (adenosine triphosphate) is a molecule that provides energy for cellular activities, including muscle contraction and biochemical reactions.

Front

What are abiotic factors?

Back

Abiotic factors are the non-living components of an ecosystem, such as sunlight, temperature, water, and soil.

Front

How do abiotic factors influence living organisms?

Back

Abiotic factors influence the growth, behavior, and survival of living organisms by affecting their habitat and resource availability.

Front

What is the significance of sunlight in an ecosystem?

Back

Sunlight is crucial for photosynthesis, allowing plants to convert light energy into chemical energy, which supports the entire food web.

Front

What role do nutrients play in the body?

Back

Nutrients provide the necessary substances for energy, growth, repair, and maintenance of body functions.

Front

What is the relationship between energy and metabolism?

Back

Metabolism is the set of life-sustaining chemical reactions in organisms, and it requires energy, primarily derived from ATP.
