Cycles
This process changes liquid water on Earth’s surface into water vapor in the atmosphere.
What is Evaporation
This is the best term for all the nonliving parts of an environment.
Abiotic Factors
These are the two main reactants of photosynthesis.
(In addition to Sunlight)
carbon dioxide and water
This is the term for a change at one trophic level that affects other levels in the ecosystem.
Trophic cascade
Between the Water Cycle, Phosphorus Cycle, Nitrogen Cycle, Carbon Cycle.... Which one does not primarily cycle into the atmosphere
Phosphorous
This process removes carbon dioxide from the atmosphere.
What is photosynthesis?
An oak tree is classified as this type of factor in an ecosystem.
What is a biotic factor
These are the two main products of photosynthesis.
What are glucose and oxygen?
What percent of energy is transferred from one trophic level to the next?
10%
Plants releasing water vapor into the atmosphere is this process.
What is transpiration?
What percent of the air we breathe is Nitrogen?
78%
Order the levels of organization
population, Biosphere, ecosystem, community, organism, atom, cell, Biome,
Atom, Cell, Organism, population, community, ecosystem, Biome, Biosphere
Plants go through both Respiration and Photosynthesis
True
How much energy is lost as heat from one trophic level to the next.
90%
Why do food chains usually have fewer organisms at the top levels?
A. Top consumers make their own food
B. Energy increases at each trophic level
C. Less energy is available as you move up trophic levels
D. Predators do not need energy
C. Less energy is available as you move up trophic levels
This process converts nitrogen gas into forms plants can use.
What is nitrogen fixation?
an organism, such as an earthworm, woodlouse, or sea cucumber, that EATS dead and decomposing plant and animal matter (detritus). They are crucial for ecosystems as they break down organic waste, speeding up decomposition, cycling nutrients, and aiding in soil structure
Detritivores
These are the two main reactants of cellular respiration.
What are glucose and oxygen?
If a mouse receives 500 units of energy, how much energy would likely be passed to the snake that eats it?
50 units of Energy
Which two biogeochemicals are prevalent in Fertilizers?
Phosphorous and Nitrogen
This process converts nitrates back into nitrogen gas and returns it to the atmosphere.
What is denitrification?
What is the difference between a Community and an Ecosystem?
Ecosystems include both abiotic and biotic factors.
Explains how photosynthesis and cellular respiration are connected.
the products of one process are the reactants of the other
Wolves are removed from an ecosystem. Deer populations increase and plants decrease. This is best described as :
Trophic Cascade
Explain how humans are putting an excessive amount of CO2 into the atmosphere
Burning fossil Fuels
