Homeostasis Storyline Review

What is an ecosystem?

• A community of living organisms interacting with their physical environment.

• A type of biome characterized by extreme temperatures.

• A collection of non-living things in a specific area.

• A group of organisms that only includes plants.

How do human activities impact ecosystems?

• They have no effect on ecosystems.

• They can disrupt natural processes and harm biodiversity.

• They improve biodiversity and ecosystem health.

• They only affect urban areas, not natural habitats.

What is homeostasis?

• The process by which living organisms maintain a stable internal environment despite external changes.

• A method of communication between cells in an organism.

• The ability of an organism to adapt to its environment over time.

• The process of breaking down food into energy.

What is the significance of the food chain?

• It shows the flow of energy and nutrients through an ecosystem, illustrating how organisms are interconnected.

• It represents the hierarchy of species in an ecosystem based on size.

• It indicates the geographical distribution of different species.

• It describes the seasonal changes in an ecosystem.

What is the difference between a habitat and a niche?

• A habitat is the role of an organism in an ecosystem, while a niche is the environment where it lives.

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

• A habitat is a type of organism, while a niche is a group of organisms.

• A habitat is the food source of an organism, while a niche is its predator.

What is carrying capacity?

• The maximum population size of a species that the environment can sustain indefinitely.

• The total number of species in a given area.

• The amount of resources available in an ecosystem.

• The rate at which a population can grow under ideal conditions.

What is the role of decomposers in an ecosystem?

• Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

• Decomposers produce energy through photosynthesis.

• Decomposers are primary producers that create food for consumers.

• Decomposers compete with plants for sunlight and nutrients.

How do pollutants affect marine life?

• Pollutants can enhance the growth of marine organisms.

• Pollutants can harm marine organisms, disrupt ecosystems, and lead to population declines.

• Pollutants have no effect on marine life.

• Pollutants only affect freshwater organisms.

What are abiotic factors?

• Living components of an ecosystem that affect non-living organisms, such as temperature and sunlight.

• Non-living components of an ecosystem that affect living organisms, such as temperature and sunlight.

• Biotic factors that enhance the growth of living organisms, like nutrients and water.

• Chemical substances that are produced by living organisms and affect their environment.

What is biodiversity?

• The total number of organisms in a given area.

• The variety of life in a particular habitat or ecosystem, including the number of different species.

• The study of how species interact with each other.

• The process of evolution in different species.
