Vocabulary
This process allows plants to use sunlight to make their own food
What is Photosynthesis
This type of energy from the sun is converted into chemical energy
What is (radiant) Light energy
This trophic level contains organisms that produce the greatest amount of energy in the food web
What are producers
What is carrying capacity
This community of living and nonliving things that interact in a specific area
What is Ecosystem
This organelle is the site of photosynthesis in plant Cells
What is Chloroplast
Only about this percent of energy is transferred from one trophic level to the next.
What is 10%
This process returns carbon to the atmosphere when organisms break down dead matter
When resources become limited, population growth shifts from exponential to this type of curve.
What is logistic growth
This term describes a group of the same species living in the same area at the same time
What is Population
These TWO products of photosynthesis are used in cellular respiration?
If a top predator decreases in a food web, this TYPE of population often increases first
What are the prey population
Nitrogen must first be converted into usable form before plants can absorb it
what are nitrates
This type of succession begins on bare rock after lava flow or glacier retreat
What is primary succession
This is the ability to do work and flows through an ecosystem from the sun to producers and consumers
What is Energy
When plants cannot get enough sunlight on the forest floor during succession, this limiting factor reduces their growth.
What is low sunlight availability
Each level has less available energy than the one below it
Burning fossil fuels increase atmospheric carbon dioxide. This contributes to this global environmental issue
What is climate change/ greenhouse effect
Forest fires benefit ecosystems by doing this to the soil
Replenishing nutrients in topsoil
What is Cellular Respiration
If carbon dioxide levels increase in the atmosphere, how does this affect the rate of photosynthesis?
In the energy pyramid, 10,000 kilocalories of energy are available at the producer level. Approximately how much energy would be available to TERTIARY consumers?
What is 10 kcal
Explain how deforestation impacts the carbon cycle
What is fewer trees=less photosynthesis=more CO2 remains in atmosphere=imbalance in carbon cycle
A population grows rapidly at first, then levels off and becomes stable. What is this type of growth called AND what causes it to level off
What is logistic growth and its because of Carrying Capacity due to limited resources
