Trophic Levels
This group always makes up the bottom level of all energy pyramids
What are Producers?
An animal that hunts, kills, and eats other animals is called this
What is a Predator?
These organisms cannot make their own food and must rely on other organisms for energy
What are Herterotroph?
(Acceptable: What are Consumers?)
Population growth trend seen only when there are no factors limiting populations
What is Exponential Growth?
What is an Organism
Organisms that have a disproportionately large impact on the stability of their ecosystem are known as these critical types of species
What is a keystone species?
This sequence shows how energy flows from producers to top consumers
What is a Food Chain?
Organisms that translate directly from Greek as "Self-Feeding"
What are Autotrophs?
Anything that prevents a population from increasing
What are Limiting Factors?
All individuals of the same species in an area
What is a population?
These consumers always eat producers and occupy the second trophic level in a food chain
What are Herbivores?
This diagram shows how multiple food chains in an ecosystem are connected and overlap
What is a Food Web?
The amount of energy that will make it to the next feeding level
What is 10%
Population growth trend only seen when a limiting factor is reached and populations stabilize
What is Logistical Growth?
All interacting living and nonliving things in an area
What is an Ecosystem?
This type of predator sits at the top of the food chain and is not hunted by any other organism
What is an Apex Predator?
When a predator eats prey and immediately reduces its population, it’s having this kind of effect on that species
What are Direct Effects?
Captured by producers through photosynthesis- all energy in an ecosystem ultimately enters as this
What is Solar Energy?
The total amount of individuals that an ecosystem can support with the current resources available
What is Carrying Capacity?
All populations of all species living in an area
What is a Community?
The chain of direct and indirect effects that ripple through an ecosystem after a keystone species is added or removed is called this
What is a Trophic Cascade?
These organisms, such as fungi and bacteria, break down dead plants and animals and recycle nutrients
What is a Decomposer?
This molecule, produced during cellular respiration, stores and provides energy for cells
What is ATP or Cellular Energy?
Populations that remain stable, without rapid growth or decline, are said to be in this balanced condition
What is Homeostasis?
Tundras, deserts, and rainforests are examples of these large regions defined by climate, plants, and animals
What is a Biome?
