Energy in Ecosystems Quizs

If the producers in an ecosystem have 1,000,000 Calories, how much will the tertiary consumer get?

• 1,000 Calories.

• 1,000 Calories

• 100,000 Calories

• 100 Calories

Which biogeochemical cycle provides energy to the organisms in an ecosystem?

• Carbon cycle because energy is transferred from one organism to another in the form of glucose (C6H12O6).

• Carbon Cycle

• Nitrogen Cycle

• Phosphorus Cycle

Describe the four major processes that occur during the water cycle: Transpiration, Evaporation, Condensation, Precipitation

• Transpiration - Liquid water evaporates from plant leaves and enters the atmosphere as a gas.

• Evaporation - Water moves into the atmosphere from a solid to a gas.

• Condensation - Water vapor in the air condenses into clouds and is changed into solid water.

• Precipitation - Water falls from the atmosphere to Earth's surface as a gas.

What is the significance of the carbon cycle in ecosystems?

• It regulates the flow of carbon among the atmosphere, land, and organisms, providing energy for life.

• It helps in the formation of ozone in the atmosphere.

• It is responsible for the water cycle in ecosystems.

• It contributes to soil erosion and degradation.

What role do decomposers play in an ecosystem?

• They break down dead organisms and recycle nutrients back into the ecosystem.

• They break down dead organisms and recycle nutrients back into the ecosystem.

• They compete with plants for sunlight and nutrients.

• They are primary consumers that eat plants.

Which trophic levels does the yellowfin tuna fill in the food web?

• Primary producer

• Secondary consumer or Tertiary consumer

• Decomposer

• Quaternary consumer

Which has more biodiversity - food chain or food web?

• Food web

• Food web

• Food pyramid

• Food cycle

What is a producer?

• An organism that uses the sun's energy to make its own food.

• A consumer that feeds on other organisms.

• A decomposer that breaks down dead matter.

• A type of animal that hunts for food.

What is an autotroph?

• An organism that makes its own food (energy) through photosynthesis.

• An organism that consumes other organisms for energy.

• An organism that relies on external sources for food.

• An organism that can survive without any energy source.

What happens to most of the energy when predation (an organism eating another organism) occurs?

• Most is lost in the form of heat and to other life processes.

• Most is stored in the predator's body for future use.

• Most is converted into chemical energy for the prey.

• Most is transferred to the environment without any loss.
