Science Gr 5 Ecosystem
Biotic : are living things like plant and animals
Abiotic : are non-living things like soil, sunlight, air, and water
Ecosystem : are all living (biotic) and non-living (abiotic) things in an environment
Population : all members of a single species in an area at a given time
Community : is made from many different populations including all the living things in an ecosystem
ecosytem
population
community
food chains : model the feeding relationships between organisms in an ecosystem and the energy in food chain starts with the sun
Producers : are organisms the use the sun's energy to make sugar and oxygen and they are the base of every food chain
Consumers : is any animal that eats plants or other animals
Herbivores : animals that eat producers ( plants ) like squirrels, some birds, some insects and grazing animals
Carnivores : animals that eat other animals like bobcats and hawks
Omnivores : are animals that eat both plants and other animals like raccoons, mice and some crabs
Decomposers : are organisms that obtain energy by consuming wastes and dead organisms like fungi, bacteria, termites and many worms' species
Scavenger : is a consumer that cats the remains of dead animals that it didn't hunt or kill like vultures, raccoons, jackals, crows and some crabs
Food web : is a network of food chains that has some links in common. Predator: is a living thing that hunts and kills other living things for food
Prey : are organisms that are eaten by predators
Energy pyramid : is a diagram that shows the amount of energy available at each level of an ecosystem
Ecosystem
--is passed on from one organism to another............. In a food chain
Waste
Sunlight
Energy
Gas
What is a consumer
An animal that does not make its own food
an animal that eats other animals
a living organism that uses sunlight t make its own food
an animal that has no known predators
Producers are ------- ---- because they get energy from the sun, make their own food, and make food for some animals
not an important part of the food chain
animals such as deer and zebras
the first part of the food chain
break nutrients down into the soil
What is a food chain
model the feeding relationships between organisms in an ecosystem
An animal that eats other animals
A living organism that is able to use sunlight to make its own food
An animal that has no known predators
Producers are ---------because they get energy from the sun, make their own food, and make food for some animals
not an important part of the food chain
animals such as deer and zebras
the first part of the food chain
break nutrients down into the soil
What is a producer
An animal that eats other animals
A living organism that uses sunlight to make its own food
An animal that only cats plants An animal that has no known predators
A carnivore is an animal that only eats meat
True
False
food chain is a series of relationships between members of an ecosystem so that ----------------can be transferred between them
food
sunlight
energy
water
An example of a food chain in a pond environment would be : algae : water bug : fish : otter. In this example the is at the bottom of the food chain
algae
water bug
fish
otter
the flow of energy in an ecosystem
Grass - cow - human
Caterpillar - leaf - human
Cow - grass
