Ecosystem Interactions and Energy Flow

What is photosynthesis?

• Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to make their own food.

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

• Photosynthesis is the method by which plants absorb nutrients from the soil.

• Photosynthesis is the way in which plants reproduce sexually.

How do animals help in the process of pollination?

• Animals, like bees, transfer pollen from one flower to another, helping plants reproduce.

• Animals provide nutrients to flowers to enhance growth.

• Animals create a protective barrier around flowers to prevent pests.

• Animals consume flowers and help in seed dispersal.

What is a food web?

• A simple linear sequence of organisms that eat each other.

• A complex network of interconnected food chains in an ecosystem.

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

• A type of food chain that only includes herbivores.

What is an invasive species?

• A native organism that supports the ecosystem.

• A non-native organism that disrupts the ecosystem.

• An organism that is beneficial to its environment.

• A species that is endangered and needs protection.

What is the water cycle?

• The process of water being stored in lakes and rivers.

• The continuous movement of water through evaporation, condensation, and precipitation.

• The method by which plants absorb water from the soil.

• The cycle of water being filtered through the ground.

What happens to the population of owls if the population of mice decreases?

• The population of owls will definitely decrease.

• The population of owls may not necessarily decrease because they have other prey.

• The population of owls will increase due to less competition.

• The population of owls will become extinct.

What is an ecosystem?

• An ecosystem is a community of living organisms interacting with their environment.

• An ecosystem is a type of plant that grows in water.

• An ecosystem is a collection of rocks and minerals.

• An ecosystem is a system of government for managing natural resources.

What is the significance of biodiversity in an ecosystem?

• Biodiversity helps maintain ecosystem balance and resilience.

• Biodiversity reduces the number of species in an ecosystem.

• Biodiversity increases competition among species.

• Biodiversity has no impact on ecosystem health.

What is a producer in an ecosystem?

• An organism that can make its own food, usually through photosynthesis.

• An organism that consumes other organisms for energy.

• An organism that decomposes dead matter.

• An organism that relies on external sources for food.

What is the role of decomposers in an ecosystem?

• Decomposers break down dead organisms and recycle nutrients into the soil.

• Decomposers produce energy through photosynthesis.

• Decomposers compete with plants for sunlight and nutrients.

• Decomposers are primary consumers that eat plants.
