Ecology 1
True or False: Secondary and Tertiary consumers are Omnivores/Carnivores
TRUE
An organism that uses sunlight to create its food
Producer
any animal that feeds mainly on plants; plant-eater
Herbivore
What do the arrows in a food chain represent?
How food/energy moves from one organism to the next
an organism that hunts, kills, and eats other organisms
Predator
True or False: A biologist studies environmental changes in an ecosystem
False
something that eats something else for food
Consumer
Where an organism lives in an ecosystem
Habitat
The living and nonliving things in an area and the ways they interact in an environment (ex: redwood forest, swamp, Mojave Desert)
Ecosystem
Food chains show...
What organisms eat in an ecosystem
An animal that eats plants or other animals and does not make its own food.
What is a consumer?
Who eats the producers in a food chain?
Primary Consumers
An organism that eats meat
Carnivore
one organism of one species
Individual
An organism that feeds on dead and decaying animals
Scavenger
An organism that gets hunted by other organisms
Prey
Plants source of energy
Sun
What happens to the energy levels as more organisms are added to a food chain?
The energy decreases
What is ecology?
The study of how organisms interact with each other and their surroundings
a relationship that involves one organism living with, on, or inside another organism and harming it
parasitism
all the species living in a particular area
What is a community?
Living organisms in an ecosystem
Biotic Factor
Are primary consumers omnivores, herbivores, or carnivores?
Herbivores
An area that is suitable for a particular organism to live in is called....
What is a habitat?
Any living thing that feeds on already broken down dead bodies of other living things and turns it into organic matter
Decomposer
The role that an organism plays in the ecosystem is called...
An organisms niche
Plants use this process to turn light into chemical energy
Photosynthesis
a relationship in which one species benefits and the other species is neither helped nor harmed
commensalism
any living thing that feeds on both plants and animals
Omnivore
Bacteria, fungi, worms, ants and beetles are all examples of....
Decomposers
An environmental factor that causes a population to stop growing or decrease in size
limiting factors
the largest population that an area can hold
carrying capacity
a relationship in which both species benefit
mutualism
any non-living thing an organism needs to survive
abiotic
Name 3 limiting factors that can cause a population to stop growing
climate, weather, space, food, and water
List the 6 levels of organization in order from species to biosphere.
1. Species, 2. population, 3. community, 4. ecosystem, 5. biome, 6.biosphere
