What adaptations do animals in the tundra have for survival?

• Heavier fur and hibernation

• Bright colors for camouflage

• Longer legs for running

• Ability to fly long distances

What is a biotic factor?

• A non-living component of an ecosystem, such as rocks and water.

• A living component of an ecosystem, such as plants, animals, and microorganisms.

• A chemical substance that affects living organisms.

• A physical feature of the environment, such as temperature and humidity.

What is an ecosystem?

• An ecosystem includes all living and non-living things in an environment, interacting as a system.

• An ecosystem is a group of similar organisms living in the same area.

• An ecosystem is a collection of different species in a specific habitat.

• An ecosystem is a network of food chains in a single environment.

What is a community in ecology?

• A community is a group of interacting populations that occupy the same space at the same time.

• A community is a collection of different species living in isolation.

• A community is a group of organisms that do not interact with each other.

• A community is a single species living in a specific habitat.

What is the significance of food chains and food webs?

• They show the geographical distribution of species.

• They illustrate the flow of energy and nutrients through an ecosystem, showing how organisms are interconnected.

• They represent the evolutionary history of organisms.

• They provide a method for classifying different types of ecosystems.

What is a niche?

• A type of habitat where organisms live

• The role or function of an organism or species within an ecosystem, including its habitat, resource use, and interactions with other organisms.

• A method of reproduction in plants

• A classification of organisms based on their size and shape.

What is biodiversity?

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

• Biodiversity is the total number of organisms in a specific area, regardless of species.

• Biodiversity is the genetic variation within a single species.

• Biodiversity refers to the number of ecosystems in a geographical region.

What role do producers play in an ecosystem?

• Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food chain.

• Producers are organisms that consume other organisms for energy.

• Producers are responsible for decomposing organic matter in the ecosystem.

• Producers are the primary consumers in the food chain.

What is a biome?

• A biome is a small area with diverse wildlife.

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

• A biome is a type of climate that affects weather patterns.

• A biome is a collection of individual species living in isolation.

What characteristics are biomes not classified by?

• Soil quality

• Climate conditions

• Vegetation types

• Geographical location
