the study of living things & their environment.
living and non-living things that live together and interact.
the surroundings of an object.
many different species living together.
occurs naturally in the area.
something not from the area and also causes harm to food web.
movement of organisms from one habitat to another
non-living things found in environment. Examples: rocks, sand, minerals, water, clouds, air, weather, pollution, sunlight, temperature
living things found in environment
a living thing. Example-me
one single organism. Example-me
One species living together in a specific area. Example-Green Crabs at Willard Beach
Many different species living and interacting in one specific area. Example-All of the plants and animals that interact at Willard Beach like the seagulls, crabs, seaweed, fish, mussels, dune grass, etc.
all the interacting feeding relationships in an ecosystem or community.
Organism that make their own food. Plants-plankton, fern or seaweed
The way that plants use the sunlight, carbon dioxide, and water to make their own food (glucose-which is energy).
Animals that eat other organisms. Example-me, seal, bird, whale....etc.
Primary Consumers (herbivore)
Animals that eat plants. Example-Zooplankton, krill, some crabs, some fish that just eat plankton, some birds, some insects.
Animals that eat only plants-Example-crab that just eats algae, cow, bunny
Animals that eat primary consumers (herbivores). Example-penguin eat krill, fish that eats plankton, owl eats mouse
Third Level Consumer
Animals that eat secondary consumers.
animal that only eats meat. Example-Leopard Seal or shark, or polar bear,
Animal that eats both plant and animal. Example -me, bears.
Organism that eats dead/decaying matter. Example-bacteria/fungus.
the different levels found in a food web
organisms that makes their own food (energy) . Also called self-feeders. Example: plants, some protitst, some bacteria
organisms that eat other organisms for energy. Example-humans
total organic matter in an ecosystem
The maximum size of a population that can be supported by a given environment.
Small parts of organic material.
A sequence of organisms that eat one another in an ecosystem.
A kind of trophic-level diagram in the shape of a pyramid in which the largest layer at the base is the producers with the first-level, second- level, and third-level consumers in the layers above.
microscopic plants that live in the ocean.
microscopic animals that live in the ocean.
