Living Things - Plants, animals and people need each other to live.  All living things need energy to live and grow.

Life Sciences

  1. All organisms need energy and matter to live and grow. As a basis for understanding this concept:
    1. Students know plants are the primary source of matter and energy entering most food chains.
    2. Students know producers and consumers (herbivores, carnivores, omnivores, and decomposers) are related in food chains and food webs and may compete with each other for resources in an ecosystem.
    3. Students know decomposers, including many fungi, insects, and microorganisms, recycle matter from dead plants and animals.

  2. Living organisms depend on one another and on their environment for survival. As a basis for understanding this concept:
    1. Students know ecosystems can be characterized by their living and nonliving components.
    2. Students know that in any particular environment, some kinds of plants and animals survive well, some survive less well, and some cannot survive at all.
    3. Students know many plants depend on animals for pollination and seed dispersal, and animals depend on plants for food and shelter.
    4. Students know that most microorganisms do not cause disease and that many are beneficial.

There are many different ecosystems on Earth.

Tundra - Frozen ground, few trees, and long, dark, cold winters.

Taiga - cold winters and cool summers with more rain and snowfall than tundra

Grasslands - cold winters and hot summers with more rain and snowfall than taiga.  Rich soil.

Prairie http://www.museum.state.il.us/muslink/prairie/htmls/eco.html National Geographic Prairie Habitat  Build A Prairie

Mild forest lands - mild winters and hot summers with plenty of rain and snow.  Trees lose leaves in winter.  National Geographic forest Habitat

Desert - very hot all year with very little rain.  Plants and animals are adapted to conserving water. What's it like where you live deserts

Tropical rain forest - hot and rainy all year with poor soil and a variety of plants and animals.

Saltwater shores - many organisms live were the water changes from high tide to low tide. National Geographic Ocean Habitat

Freshwater rivers - Many habitats are along the shore and river bottoms.  Freshwater lakes and ponds - many habitats are at the shore, on surface water, and under the water.  National Geographic Freshwater Habitats
