Things are Found
Environment: everything around a living thing
All living things need food, water, air and shelter.
Many living things can share an environment and thus must also share the things they need to live.
Living Things: any thing that needs food, water, air and shelter
Ecosystem: the living and nonliving things that affect each other or interact
Example : pond
Population: a group of the same kind of living things that live in the same place at the same time.
Community: All the populations that live in an ecosystem.
Habitat: the home of all the living things that make up the community (provides all the needs including living and nonliving things)
The ecosystem of this pond is made up of all the living and nonliving things that interact in and around the pond.
Nonliving things , such as air, sunlight, water, rocks and soil are also part of ecosystem. The community of living things needs the nonliving things to survive.
Pond is the habitat or home of all living things that make up the community.
The edge of the pond is the habitat for the cattails.
2 ways an ecosystem can change:
Forest: area in which the main plants are trees
Some forest named for types of trees that grow in them or the area in which they grow.
Deciduous Forests are forest made up mostly of trees such as maples and oaks.
Desert: an ecosystem found where there is very little rainfall. (less than 25 cm. per year)
Water ecosystem covers more than 70 % of Earth’s surface
Salt Water: water that has a lot of salt in it
Oceans and seas (plus marshes and a few lakes) have salt water - these are called Saltwater ecosystems
Fresh water: water that has very little salt in it.
Lakes, rivers, ponds, streams and marshes – are freshwater ecosystems
Tide Pool: saltwater ecosystem that forms near shoreline
Oceans are Earth’s largest ecosystem
Ocean divided into zones (how much sunlight it gets)
Main freshwater ecosystems are rivers, streams, lakes and ponds
As in ocean, most plants and animals in a lake or pond live in the shallow water. The fewest plants and animals live where the water is too deep for sunlight to reach the bottom.
