Ecology Unit Quick Reference Name: ________________________

Big Idea: How energy moves through biotic and abiotic things

Ecology Standard: Stability in an ecosystem is a balance between competing effects.

Learn for mastery: Students will be able to

explain the various cycles (carbon, water, nitrogen, & phosphorus) and their

impact on ecosystem.demonstrate links within food chain & food web.

understand and analyze how the alteration of habitats impacts different kinds of

organisms.know that mitochondria liberate energy for the work that cells do & that

chloroplasts capture light for photosynthesis.

how organisms utilize the energy captured from photosynthesis in cellular

respiration.

explain how organisms can accommodate or adapt to environments.determine solutions and/or supports for maintaining a healthy ecological

balance.identify what factors impact/determine fluctuations in population size in an

ecosystem.

Unit Outline:

Ecology Cycles Food Chain

Food Web Photosynthesis Respiration Relation to food chain/web

Test #1: Cycles & levels of organization

Topic: The Biosphere/Energy Flow (Chp. 3 study guide pg. 82)

Key Vocabulary =

3.1 ecology, biosphere, species, population, community, ecosystem, biome3.3 nutrient, denitrification, nitrogen fixation, evaporation, transpiration

Key Concepts =

1.3 characteristics of living things; levels of organization3.1 ID levels of organizations that ecologists study

3.3 how matter cycles among living and nonliving parts of ecosystem

(pgs. 75 water cycle, 77 carbon cycle, 78 nitrogen cycle, 79phosphorus cycle); describe how availability of nutrients effects

productivity of ecosystems
