Bill Moyers Reports: Earth on Edge - Ecosystems Ecosystems are communities of interacting organisms and the physical environment in which they live. They are the combination and interaction of the plants, animals, minerals, and people in any given area of the Earth. A small bog, a single sand dune, or a tiny patch of forest is an ecosystem.

Fitting Algae Into the Food Web The food web you created in the food web game was one that is found in the Antarctic. As you might imagine, a food web in the tropics looks very different from the one you created. Environmental conditions (temperature, light, nutrients) are different in the two areas, so it would make sense that the organisms that live in those areas might be different also.

Earth Floor: Biomes There are many different kinds of plants and animals on the Earth, but only certain kinds are naturally found at any particular place. (We are not counting zoos here!) For example, cacti are found in the desert, polar bears are found in the Arctic, and elephants are found in central Africa and India. So, why don't people living in south Texas have to be on the lookout for snow leopards, or why don't kids in Minnesota have to worry about finding giant boa constrictors in their back yards?

An ecosystem is a group of plants, animals, and other living things that live in the same surroundings.

"Pea Soup" - Pea Experiment This is an interactive pea experiment where you can breed your own hybrid pea plants! You will start with two parent plants and end up with four child plants *. Pick two of those to breed together for four new children, and so on. (Note: you can breed a plant with itself.) There are two attributes passed between generations in this simulation. These are the out of the seven main attributes studied by Mendel: Journey to Planet Earth . Ecosystems We are intimately familiar with ecosystems. They are the woodlands where we live, hunt, cut timber, or hike; the lakes, streams, and rivers we fish, boat, transport our goods on, and tap for water; the rangelands where we graze our cattle; the beaches where we play, and the marine waters we trawl; the farmlands we till; even the urban parks and green spaces we stroll. In effect, every centimeter of the planet is part of an ecosystem. Ecosystems are:

Mitosis: An Interactive Animation This animation demonstrates the stages of mitosis in an animal cell. Use the control buttons along the bottom to run the complete animation. Click on any intermediate stage (for example, Anaphase), and see a representative still frame. Interphase: Cells may appear inactive during this stage, but they are quite the opposite. This is the longest period of the complete cell cycle during which DNA replicates, the centrioles divide, and proteins are actively produced. For a complete description of the events during Interphase, read about the Cell Cycle.
