Vocabulary Part 2
100
The scientific study of interactions among organisms and between organisms and their environment, or surroundings.
What is Ecology?
100
Sunlight
What is the main energy source for life on Earth?
100
biological, geological, and chemical
Where does biogeochemical cycles connect to?
100
A group of ecosystems that have the same climate and similar dominant communities.
What is a biome?
100
I is a group of heterotrophs and it breaks down organic matter.
What are decomposers?
200
Individual/species, Population, Community, Ecosystem, Biome, Biosphere
What are the levels of organization?
200
Energy flows through an ecosystem in one direction, from the sun or inorganic compounds to autotrophs (producers) and then to various heterotrophs (consumers)
How does energy flow through living systems?
200
It is the process by which water changes from liquid form to an atmospheric gas.
What is evaporation?
200
It obtains energy by eating only plants. For example, cows, caterpillars, and deer.
What is the definition of a herbivore?
200
It is the process of releasing nitrogen into the atmosphere once again.
What is denitrification?
300
Observing, Experimenting, and Modeling
What are the ecological methods?
300
Food chains end and food web recycle energy.
What is a difference between a food chain and a food web?
300
To grow and carry out essential life functions.
Why do every living organism needs nutrients?
300
When organisms use chemical energy to produce carbohydrates.
What is chemosynthesis?
300
When bacteria, which live in the soil and on the roots of plants called legumes, convert nitrogen gas into ammonia.
What is a nitrogen fixation?
400
Species/ Individual, Population, Community, Ecosystem, Biome, Biosphere
What are the levels of organizations?
400
They use energy from their environment to fuel the assembly of simple inorganic compounds into complex organic molecules.
What are producers?
400
It doesn't enter the atmosphere.
What is different about Phosphorus cycle compared to the nitrogen cycle and the carbon cycle?
400
A step in a food chain or a food web.
What is a trophic level?
400
Is when plants create their own nutrients.
What is a photosynthesis?
500
Because to gain insight into complex phenomena such as the effects of global warming on ecosystems.
Why do they use modeling?
500
10 percent
How much energy is available within one trophic level to organisms at the next trophic level?
500
When an aquatic ecosystem receives a large input of a limiting nutrient, the result is often an increase in the number produces.
When does algal bloom occur?
500
When water enters the atmosphere by evaporating from the leaves of plants.
What is transpiration?
500
A pyramid that represents the amount of living organic matter at each trophic level.
What is a biomass pyramid?
