Biomes

Biomes of the World

What makes one area of the Earth support a certain biome, while another area cannot? The climate is the main factor. Rain fall amounts and temperature are the most important climate factors for why an area is a certain biome. The type of soil has an effect too.

NGSS Life Science Progression Standards K-12

LS2.A Interdependent Relationships in Ecosystems
K-2 Plants depend on water and light to grow, and also depend on animals for pollination or to move their seeds around.
3-5 The food of almost any animal can be traced back to plants. Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants, while decomposers restore some materials back to the soil.
6-8 Organisms and populations are dependent on their environmental interactions both with other living things and with nonliving factors, any of which can limit their growth. Competitive, predatory, and mutually beneficial interactions vary across ecosystems but the patterns are shared.

LS2.C Ecosystem Dynamics, Functioning, and Resilience

K-2 N/A
3-6 When the environment changes some organisms survive and reproduce, some move to new locations, some move into the transformed environment, and some die.
6-8 Ecosystem characteristics vary over time. Disruptions to any part of an ecosystem can lead to shifts in all of its populations. The completeness or integrity of an ecosystem’s biodiversity is often used as a measure of its health.
