Abiotic and biotic
100

When analyzing a graph, this is how you would describe a trend when the number of organisms are staying relatively the same over time.

remain stable

100
What eats plants and wheat/ makes own food
What is producer
100

This gas molecule, produced during photosynthesis, is essential for cellular respiration in many organisms

Oxygen

100

This concept describes the limit to the number of organisms an ecosystem can support.

carrying capacity

100
Things that aren't alive
What is abiotic
200

What is the graph where one population is increasing while at the same time the other is decreasing

Predator/prey curve

200
What eats producers and other consumers
What is third level consumer
200

This process converts light energy into chemical energy stored in glucose

Photosynthesis

200

These factors, such as resources or predation, can limit the size of a population in an ecosystem.

Limiting factors
200

These biotic components break down dead organisms and return nutrients to the ecosystem

decomposers

300

When analyzing a graph, this is how you would describe a trend when the number of organisms are getting lower over time

decrease

300
An animal/ human that eats food of both plant and animals.
What is omnivore
300

This rule explains the energy transfer between trophic levels, indicating that only a fraction of energy is transferred to the next level.

10% rule

300

This type of growth graph can be seen in a population if the environment has unlimited resources. 


Exponential growth

300
Things that are alive
What is biotic
400

This type of population growth is limited by resources, and population growth slows and stabilizes as it approaches carrying capacity

logistic growth

400
Herbivore
What is an animal that eats plants
400

These organisms play a key role in the nitrogen cycle by converting atmospheric nitrogen into usable forms for plants.

Bacteria

400

Human activities, like pollution and deforestation, are known as this type of change to the environment.

negative change

400

This abiotic factor is essential for photosynthesis, providing the energy for most food chains

Sun/sunlight

500

When analyzing a graph, this is how you would describe a trend when the number of organisms are getting higher over time.

increase

500
Animals that eat producers
What is a first level consumer
500

What are the 2 models that show how matter cycles through an ecosystem often include these three elements.

Carbon and Nitrogen

500

The introduction of these species can disrupt an ecosystem and threaten the survival of native species.
