- What is a biome?
- A group of ecosystems that have the same climate and similar dominant communities.(pg64,98)
- What is a canopy?
- A canopy is a dense covering formed by the leafy tops of tall rain trees.(p 100)
- What is a deciduous tree?
- A tree that sheds its leaves during a particular season each year(p 100)
- What is humus?
- Humus is material formed from decaying leaves and other organic matter(p 103)
- What is permafrost?
- Permafrost is a layer of permanently frozen subsoil in the tundra(p 104)
- What is a microclimate?
- A climate within a small area that differs signigicantly from the climate of the surrounding area.(p 98)
- What is understory?
- It is a layer in a rain forest formed by shorter trees and vines.(p100)
- What is a coniferous tree?
- Trees that produce seed-bearing cones and have thin leaves shaped like needles.(p103)
- The Role of Climate
- Carbon dioxide, methane, water vapor, and a few other atmospheric gases trap heat energy and maintain Earth's temperature range
- What are the three major climate zones?
- As a result of differences in latitude and thus the angle of heating, Earth has three main climate zones: polar, temperate, and tropical.
- What Shapes an Ecosystem?
- Together, biotic and abiotic factors determine the survival and growth of an organism and the productivity of the ecosystem in which the organism lives.
- What can affect an ecosystem?
- Comunity interactionsm such as competition, predation, and various forms of symbiosis, can powerfully affect and ecosystem.
- What is predation?
- Predation is interaction in which one organism captures and feeds on another organism(p93)
- Explain how ecosystems are constantly changing.
- Ecosystems are constantly changing in response to natural and human disturbances. As a ecosystem changes, older inhabitants gradually die out and new organisms move in, causing further changes in the community.
- What are the world's major land biomes?
-
Tropical rain forest, tropical dry forest, tropical savanna.
Temperate grassland, desert, terperate forest, northwestern coniferous forest, boreal forest and tundra. - What determines an Aquatic Ecosystem?
- Aquatic ecosystems are determined primarily by the depth, flow, temperature, and chemistry of the overlying water.
- What are the two main types of freshwater ecosystems?
- The two main types are, flowing-water ecosystems and standing-water ecosystems
- What are divisions of ocean?
- Division of the photic and aphotic zones and marine biologists also divide it into zones based on the depth and distance from shore: the intertidal zone, coastal ocean, and the open coean.
