12/11 Exam Review

Front

What is Consumption in ecological terms?

Back

Consumption refers to the process by which herbivores feed on photosynthetic plants, transferring energy and nutrients up the food chain.

Front

Define Assimilation in the context of plant and animal nutrition.

Back

Assimilation is the process by which plants absorb nutrients, such as proteins, through their roots, which are then passed on to animals when they consume the plants.

Front

What is Condensation in the water cycle?

Back

Condensation is the process where water vapor cools and changes into liquid water, forming clouds.

Front

Identify the process represented by Denitrification in the nitrogen cycle.

Back

Denitrification is the process by which nitrogen compounds are converted back into nitrogen gas, returning it to the atmosphere.

Front

Explain the role of greenhouse gases in the greenhouse effect.

Back

Greenhouse gases, such as carbon dioxide, methane, and water vapor, allow sunlight to enter the atmosphere, but trap heat by reflecting it back to the Earth's surface, preventing excessive cooling.

Front

What is the significance of Biodiversity in ecosystems?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, which contributes to resilience and stability.

Front

Define Nitrogen Fixation.

Back

Nitrogen fixation is the process by which atmospheric nitrogen is converted into a form usable by living organisms, often facilitated by certain bacteria.

Front

What is the difference between Evaporation and Transpiration?

Back

Evaporation is the process of water turning into vapor from surfaces like lakes, while transpiration is the release of water vapor from plant leaves.

Front

Describe the process of Ammonification.

Back

Ammonification is the conversion of organic nitrogen from dead organisms into ammonia, which can then be used by plants.

Front

What is Nitrification?

Back

Nitrification is the process by which ammonia is converted into nitrites and then nitrates, which are usable forms of nitrogen for plants.
