The Water Cycle
Shaping of Ecosystems
100
This is the largest ecological level.
What is the biosphere?
100
These organisms can create food for themselves from chemicals or sunlight.
What are autotrophs?
100
This is a series of steps in which organisms transfer energy by eating and being eaten.
What is a food chain?
100
This is the process by which water changes from liquid form to vapor form.
What is evaporation?
100
This is the full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions (there is only one of these per species).
What is a niche?
200
This is the second largest ecological level and includes groups such as the taiga and grasslands.
What are biomes?
200
In an ecosystem, this group creates the energy, food, and organic compounds for the higher groups that consume the group.
What are producers?
200
This links all of the food chains in an ecosystem together.
What is a food web?
200
This is the process in which water evaporates through the leaves of plants.
What is transpiration?
200
This states that no two species can occupy the same niche in the same habitat at the same time.
What is the competitive exclusion principle?
300
This level is a collection of all the organisms that live in a particular place.
What is an ecosystem?
300
This is the main energy source for life on earth.
What is sunlight?
300
Each step in a food chain or food web is called this.
What is a trophic level?
300
Plants take in water from the ground by using this process.
What is root uptake?
300
In this form of symbiosis, one member of the association benefits while the other is neither helped or harmed.
What is commensalism?
400
This level is a group of individuals that belong to the same species.
What are populations?
400
The process used by autotrophs to create carbohydrates from chemical energy.
What is chemosynthesis?
400
This is a consumer which only consumes plants.
What is an herbivore?
400
This is the process between evaporation and precipitation and it results in the creation of a cloud.
What is condensation?
400
In this form of symbiosis, one organism lives inside or on another organism and harms it.
What is parasitism?
500
These are assemblages of different populations that live together in a defined area.
What are communities?
500
This group of heterotrophs breaks down organic matter.
What are decomposers?
500
This body of water is a result of seepage in which water seeps into the ground and can be taken up by plants.
What is ground water?
500
This is the series of predictable changes that occurs in a community over time.
What is ec
