Introduction to Ecology Quiz

What is an ecosystem?

• A type of clothing worn in extreme weather conditions

• A community of living organisms in conjunction with the nonliving components of their environment

• A new type of musical instrument

• A type of computer software

Explain the concept of a food chain in an ecosystem.

• A food chain in an ecosystem is a chain of restaurants that serve organic food.

• A food chain in an ecosystem refers to the process of growing food in a controlled environment.

• A food chain in an ecosystem is a physical chain made of food items found in the environment.

• A food chain in an ecosystem shows the flow of energy and nutrients from one organism to another.

Describe the role of producers in an ecosystem.

• Producers convert sunlight into energy through photosynthesis and form the base of the food chain.

• Producers only produce oxygen

• Producers have no role in the ecosystem

• Producers consume energy from other organisms

How do abiotic factors influence an ecosystem?

• Abiotic factors directly impact the living organisms and their interactions within an ecosystem.

• Abiotic factors only affect non-living things in an ecosystem

• Abiotic factors have no impact on an ecosystem

• Abiotic factors only influence a small portion of an ecosystem

What are the major types of biomes?

• Savanna, Tundra, Desert, Ocean

• Tundra, Taiga, Temperate Deciduous Forest, Grassland, Desert, Tropical Rainforest, Aquatic Biomes

• Polar, Rainforest, Steppe, Alpine

• Jungle, Prairie, Arctic, Savannah

Explain the characteristics of a tropical rainforest biome.

• Tropical rainforest biome is characterized by high rainfall, high humidity, and a wide variety of plant and animal species.

• Tropical rainforest biome is characterized by low rainfall and low humidity.

• Tropical rainforest biome is characterized by a lack of biodiversity and limited plant and animal species.

• Tropical rainforest biome is characterized by extreme cold temperatures and little vegetation.

Describe the adaptations of plants and animals in a desert biome.

• Plants have no root systems, no water-storing tissues, and increased leaf surface area. Animals have nocturnal behavior, inefficient water conservation, and heat intolerance.

• Plants have deep root systems, no water-storing tissues, and increased leaf surface area. Animals have diurnal behavior, efficient water conservation, and cold tolerance.

• Plants have deep root systems, water-storing tissues, and reduced leaf surface area. Animals have nocturnal behavior, efficient water conservation, and heat tolerance.

• Plants have shallow root systems, water-storing tissues, and increased leaf surface area. Animals have diurnal behavior, inefficient water conservation, and cold tolerance.

What are the different trophic levels in an energy pyramid?

• Producers, primary consumers, secondary consumers, and tertiary consumers

• Decomposers, scavengers, parasites, mutualists

• Autotrophs, heterotrophs, saprotrophs, mixotrophs

• Herbivores, carnivores, omnivores, detritivores

Explain the concept of energy flow in an ecosystem.

• The migration of animals in search of food

• The process of photosynthesis in plants

• The transfer of energy from one organism to another through food chains and food webs.

• The movement of water through the ecosystem

How do decomposers contribute to the energy flow in an ecosystem?

• By hunting and consuming other organisms for energy

• By competing with other organisms for resources

• By providing shelter and protection for other organisms

• By breaking down dead organisms and organic matter, releasing nutrients back into the ecosystem for other organisms to use.
