Ecology-Biomes Organisms and Their Environments

Objectives I can describe the factors that determine biomes I can identify limiting factors for terrestrial and aquatic biomes I can define with examples habitats and niches

Biomes Defined by climate (abiotic factors) Temperature Moisture, etc. Plants (photosynthetic) Food Habitat

Biome - Biotic Factors When thinking about biodiversity What limits plant/photosynthetic life How much habitat is provided The bigger/more green stuff…

Copy into notebook

Dominant Plant Type (food type) Producer (photosynthetic) Conversion of sunlight to food Base of food chain Also (usually) provides shelter/habitat

Niche vs. Habitat

Habitat The place where the organism lives. Includes the space, food, and other conditions the organism needs to survive.

Niche The role a species plays in a community. How it uses its habitat

Bay-Breasted Warbler Feeds in the middle part of the tree Yellow-Rumped Warbler Feeds in the lower part of the tree and at the bases of the middle branches Cape May Warbler Feeds at the tips of branches near the top of the tree Spruce tree

NOTE: Several species may share a habitat, but the food, shelter, and resources of that habitat are divided into separate niches.

Quick review

n What is the portion of the earth that supports life called? n Give 2 examples of abiotic factors. n What do you call the role a species plays in its environment? Biosphere Niche

n What is formed by several populations that interact with each other? n What do you call a community and its abiotic factors? n List the levels of biological organization from smallest to largest. Community Ecosystem IPCEBIPCEB
