Biomes And Ecosystems

A habitat is the place where a population lives. A population is a group of living organisms of the same kind living in the same place at the same time. All of the populations interact and form a community. The community of living things interacts with the non-living world around.

Ecosystems are dynamic interactions between plants, animals and microorganisms and their environment working together as a functional unit. Ecosystems will fail if they do not remain in balance.
Every time we walk out in the wilderness or bulldoze land for a new parking lot, we are drastically altering an ecosystem. We have disrupted the food chain, the carbon cycle, the nitrogen cycle and the water cycle. Everything in the natural world is connected. An ecosystem is a community of living and non-living things that work together. We're all in this together. The water, water temperature, plants, animals, air, light and soil all work together.

Biomes are defined as "the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment". Biomes are the world's major habitats. These habitats are identified by the vegetation and animals that populate them. The location of each biome is determined by the regional climate. Some climates are hot, some are cold, some are wet and some are dry. "Adapted" means that a plant or animal has inherited certain characteristics that enable it to live in one type of climate or another.

Over the past several decades, increasing human activity has rapidly destroyed or polluted many ecological habitats throughout the world.
