Ecosystem Hierarchy
This is the largest most broad level of ecosystem hierarchy relating to the entire planet
what is biosphere?
What trophic level is responsible for converting solar energy into chemical energy?
producers
What is the meaning of heterotroph?
An organism that cannot create its own food it must consume it
What is the difference between a predator and prey animal?
The predator eats the prey, the prey gets eaten by the predator
What is the source of all energy in an ecosystem?
the sun
This is the smallest most zoomed in level relating to one
what is organism or individual?
What is another word that has the same meaning at producer
Autotroph
What is the name for an organism that only eats plants?
What is the name for an organism that only eats animals?
Only plants= Herbivore
Only animals= carnivore
What is carrying capacity?
The total number of organisms an ecosystem can support without hurting the environment
What group of organisms is responsible for recycling energy by consuming dead things and breaking them down
Decomposers (detritivores and scavengers too)
Which of these is a population:
All of the white tailed deer in a forest
All of the animals and plants in a forest
All of the abiotic and biotic factors in a forest
What is "all of the white tailed deer in a forest"?
What are the reactants necessary for photosynthesis (3)
Sunlight, water, and carbon dioxide
What is the name for an organism that consumes both animals and plants?
Omnivore
Why is it good for prey populations to have predators?
It keeps their population in check so they do not overconsume their food (usually plants) and make it go extinct
What is the type of energy transfer that occurs in an ecosystem? It goes from ________ energy to _________ energy.
It goes from solar energy to chemical energy
Which of the following best represents a community:
A rabbit
A grassland
All the rabbits in a grassland
All the rabbits, insects, and plants that live together in a grassland
What is "All the rabbits, insects, and plants that live together in a grassland"?

there are 4 kingdoms of life that make up heterotrophs 2 are protists and bacteria, what are the other 2
animals and fungi
1. Predation
2. Disease and parasites
3. Food and water availability
4. Shelter/space
What trophic level receives the least amount of energy? AND What trophic level receives the most?
Least= quaternary consumers
Most= Producers
Tell me the 6 levels starting from most broad to most specific
Biosphere, Biome, Ecosystem, Community, Population, Organism/Individual
What do the arrows in a food web/chain represent
The direction of the flow of energy
Tell me the 5 trophic levels from base of food chain to top
Producer, primary consumer, secondary consumer, tertiary consumer, quaternary consumer
What are the 4 important facts about predator and prey relationships
1. There is always more prey that predator
2. Predator populations lag behind prey populations
3. Predator populations control prey by keeping them down
4. Prey populations control predators by providing a food source
Tell me the % of energy available to each level of an energy pyramid
Primary consumers 10%
Secondary consumers 1%
Tertiary consumers 0.1%
Quaternary consumers 0.01%
