What is the difference between a habitat and a niche?

• A habitat is the role of an organism within its environment, while a niche is the environment where an organism lives.

• A habitat is the environment where an organism lives, while a niche is the role or function of that organism within its habitat.

• A habitat is a type of organism, while a niche is a group of organisms that share the same environment.

• A habitat is the food source of an organism, while a niche is the space it occupies.

What is the basic unit of life?

• The atom

• The molecule

• The cell

• The organ

What is a biome?

• A biome is a large geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions.

• A biome is a small area with a unique climate and specific species.

• A biome is a type of ecosystem that only includes aquatic life.

• A biome is a region characterized by a single type of plant species.

What is an adaptation?

• A type of food that organisms eat.

• A characteristic or trait that helps an organism survive and reproduce in its environment.

• A method of communication between species.

• A seasonal change in an organism's behavior.

What is photosynthesis?

• Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

• Photosynthesis is the process of converting oxygen into carbon dioxide in plants.

• Photosynthesis is the method by which animals convert food into energy.

• Photosynthesis is the way plants absorb water from the soil.

What is the water cycle?

• A continuous process by which water evaporates, condenses, and precipitates back to the Earth.

• A method of water purification used in industrial processes.

• A cycle that describes the movement of water through the soil only.

• A phenomenon that occurs only in tropical regions.

What is a food chain?

• A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

• A food chain is a circular path that represents the movement of water in an ecosystem.

• A food chain is a diagram that illustrates the different habitats of organisms in an ecosystem.

• A food chain is a list of all the organisms in a specific area without showing their relationships.

What is an ecosystem?

• A community of living organisms interacting with their physical environment in a specific area.

• A type of plant that grows in water.

• A method of farming that uses technology to enhance crop production.

• A geographical region defined by its climate and weather patterns.

What happens if a species in an ecosystem goes extinct?

• It has no effect on the ecosystem.

• It can disrupt the food chain and affect the survival of other species that depend on it for food or other resources.

• It leads to an increase in biodiversity.

• It causes other species to thrive immediately.

What is a food web?

• A simple chain of organisms that eat one another.

• A complex network of interconnected food chains in an ecosystem, showing how different organisms are related through feeding relationships.

• A diagram that shows the energy flow in a single species.

• A list of all the plants and animals in a specific area.
