Ecosystem: A group/community of organisms interacting with their

Endangered Species: Animals or Plants facing possible extinction
in the wild (the danger of no longer existing in the wild)
Food chain: The feeding relationships of species that transfer energy
through the organisms in a community.
Food web: The complex interconnection of food chains in an

Habitat: The local environment in which a specified organism,
population, or species lives, characterized by physical and chemical
features, and the presence of certain other species.

the food chain, being eaten by filter feeders and larger larvae.
Pesticides: Chemicals used to prevent insects and other crops from
destroying crops.
Pollution: Human and natural contamination of the environment by
chemicals or heat energy to the extent that existing habitats are
threatened or populations of organisms are endangered.
Population: A group of organisms of the same species that live in
the same area at the same time
Predator: An organism that kills and consumes another organism
(prey); includes animals eating other animals, and animals eating
plants.
Prey: An organism that is killed and eaten by another organism.
Producer: An organism that makes its own food
River: A natural stream of water with a large volume
Sea: A large body of water but smaller than on ocean
Solar energy: Energy from the Sun in the form of light and heat
energy.
Threatened Species: are animals or plants that are likely to be
endangered if factors threatening it are not reversed or removed.
Water cycle: The process, involving evaporation and condensation,
by which the Earth's water circulates through the environment.
If you like, feel free to write a paragraph using six to seven of the vocabulary items and post it to your blog.
