Ecosystem Part 1 (General Principles in Ecology)

is a community of different living organisms in conjunction with the nonliving components of their environment, interacting as a system.

It is a collection of all organisms that live in a particular place together with their nonliving environment.

• Scientific study of the interactions or relationships between organisms and the environment

is a collection of plants and animals that have common characteristics for the environment they exist in.

are distinct biological communities that have formed in response to a shared physical climate.

The term “biome” was first used in ____ by ______ an American ecologist, to describe the plants and animals in a given habitat.

is smaller than a biome because a biome is distributed throughout the Earth.

are large, geographically defined regions with similar climate and vegetation, encompassing multiple ecosystems

, are localized communities of living organisms and their interactions within a specific area, often found within biomes.

An area’s biome is determined mostly by its __________ (temperature and precipitation)

is a major factor in determining types of life that reside in a particular biome

Several factors that influence climate:

LAND (6)

WATER (2)

• Often named for major physical or climatic factors and for vegetation • Characterized by distribution, precipitation, temperature, plants, and animals

There are 2 main types of rain forests:

having moderate temperatures.

Are found in eastern North America, northeastern Asia, and central and western Europe.

TEMPERATE RAIN FORESTS: Receives more than _________ (10 ft) of rain per year

• Found in regions close to the equator • Warm and humid all year long. • Lots of precipitation. • Diverse plant growth.

A leafy roof formed by the tallest trees.

A second layer of shorter trees and vines.

plants grow well in the shade formed by the canopy, but the forest floor is nearly dark and only a few plants live there.

slow plant growth; low species diversity; slow nutrient recycling and lack of water
