Geo ScienceChapter 12 Physical Environment and Introduction to Physical Geography

By: AshLynn Cowles

OBJECTIVE 1

Compare and contrast ecology and biogeography

Define ecology and biogeography

Biogeography – the study of geographical distribution of living things

Ecology – branch of biology dealing with relations between organisms and their environment and other organisms

OBJECTIVE 2

Describe habitat and niche and how they relate to one another. Define habitat and niche Compare and contrast them

Habitat- natural environment of an organism, a place that is natural for the life and growth of an organism.

Niche - position or function of an organism in a community of plants and animals

OBJECTIVE 3

Explain how habitats are occupied by plants and animals. describe how plants and animals make up a habitat.

Any source of food, water, and living things make up a habitat Ex: Oceans, Forests, Deserts, Tundra, and Wet lands

OBJECTIVE 4 Describe the processes of photosynthesis,

transpiration, and respiration. Define photosynthesis, transpiration, and

respiration Explain how all of their processes begin and

end

Photosynthesis: The process of converting solar energy, water, and carbon dioxide, into carbohydrates and oxygen

Obj 4 (cont) Transpiration: the loss of

water from plants, acts to cool the plant by releasing latent energy

Respiration: the process of “burning” stored chemical energy basically through oxidation for maintaining plant metabolism
