Ecological Pyramids Quiz

What is an energy pyramid and how does it represent the flow of energy in an ecosystem?

• It represents the flow of energy in an ecosystem by showing the transfer of energy from the sun to the earth's atmosphere

• It represents the flow of energy in an ecosystem by showing the transfer of energy from herbivores to carnivores

• It represents the flow of energy in an ecosystem by showing the transfer of energy from the soil to the plants

• It represents the flow of energy in an ecosystem by showing the transfer of energy from producers to primary consumers, and then to higher level consumers.

Explain why the energy available at each trophic level decreases as we move up the energy pyramid.

• Energy is stored in the form of fat in organisms

• Energy is created at each trophic level

• Energy is lost as heat through respiration and used for metabolism.

• Energy is transferred from the sun to the organisms

Describe one real-life example of an energy pyramid in an ecosystem.

• Desert ecosystem with cacti, scorpions, and snakes

• Grassland ecosystem with producers, herbivores, and carnivores

• Ocean ecosystem with algae, fish, and whales

• Forest ecosystem with trees, birds, and insects

What is a biomass pyramid and how does it differ from an energy pyramid?

• A biomass pyramid shows the population of organisms at each trophic level, while an energy pyramid shows the total mass of living organic matter at each trophic level.

• A biomass pyramid shows the amount of energy available at each trophic level, while an energy pyramid shows the total mass of living organic matter at each trophic level.

• A biomass pyramid shows the total mass of living organic matter at each trophic level, while an energy pyramid shows the population of organisms at each trophic level.

• A biomass pyramid shows the total mass of living organic matter at each trophic level, while an energy pyramid shows the amount of energy available at each trophic level.

Explain the concept of ecological efficiency in the context of a biomass pyramid.

• Ecological efficiency is the process of converting sunlight into energy in an ecosystem.

• Ecological efficiency is the percentage of energy transferred from one trophic level to the next in a biomass pyramid.

• Ecological efficiency refers to the total amount of biomass in a trophic level.

• Ecological efficiency is the measure of biodiversity in a specific ecosystem.

What is a number pyramid and how does it differ from energy and biomass pyramids?

• A number pyramid shows the number of clouds in an ecosystem, while energy and biomass pyramids represent the flow of sunlight and the amount of oxygen at each trophic level.

• A number pyramid shows the number of organisms at each trophic level in an ecosystem, while energy and biomass pyramids represent the flow of energy and the amount of biomass at each trophic level.

• A number pyramid shows the number of planets in an ecosystem, while energy and biomass pyramids represent the flow of air and the amount of minerals at each trophic level.

• A number pyramid shows the number of rocks in an ecosystem, while energy and biomass pyramids represent the flow of water and the amount of soil at each trophic level.

Describe the relationship between the number of organisms and the trophic levels in a number pyramid.

• The number of organisms increases as we move up the trophic levels.

• The number of organisms decreases as we move up the trophic levels.

• The number of organisms remains the same across all trophic levels.

• The number of organisms is not related to the trophic levels in a number pyramid.

What are trophic levels and how do they relate to the concept of ecological pyramids?

• Trophic levels are hierarchical levels in an ecosystem, and they relate to the concept of ecological pyramids by representing the flow of energy between different levels of the food chain.

• Trophic levels are different layers of the atmosphere, and they relate to ecological pyramids by controlling the weather patterns.

• Trophic levels are types of soil in an ecosystem, and they relate to ecological pyramids by determining the fertility of the land.

• Trophic levels are stages of plant growth, and they relate to ecological pyramids by influencing the color of leaves.
