Activity #83: A Suitable Habitat
Challenge: What are some of the important non-living characteristics of a
habitat?
Hypothesis: Some important non-living characteristics of a habitat are
soil, rocks, water, temperature and precipitation.
Vocabulary:
1. Habitat: an environment that meets the requirements for the place in
which a species can live. (the natural home or environment of an animal,
plant or other organism)
2. Population: a group of species living in the same habitat
3. Ecosystem: the interaction between communities of living things and the
nonliving environment
4. Biome: the interaction of climate, geography, and plant and animal life.
While similar biomes may exist in different parts of the world, the
ecosystems within them are not the same.
Analysis 4-7:
4. What are 2 common biomes in the United States? Where are they
located?
-Grassland and deciduous forest cover the majority of the continental
United States. **Taiga and coniferous forest cover most of Alaska.
5. Draw a diagram that shows the relationship among ecosystems,
habitats, biomes, populations, and communities.
Biome (freshwater)
Habitat (pond substrate)
Ecosystem
Community (pond)
Populations (black worms)
6. Choose one of the biomes, and explain how serious damage to this
biome would affect ecosystems on earth.
-Freshwater: no drinking water
-Marine: primary consumers increase decrease population at bottom
of food chain
-Desert: lose many species of plants
-Tundra: lose many species of animals
-Taiga (coniferous forest): lose one of our sources for wood and many
animal species
-Deciduous forest: lose one of our sources of wood and many animal
species
-Grassland: lose many species of animals
-Tropical Rain Forest: lose many species of plants (some may be
helpful in developing medicines)
7. Reflection: Do you think that introduced species are always successful
in new environments? Explain.
-Introduced species are not always successful in new environments.
What characteristics must a species have in order to be successful?
-reproduce quickly
-tolerate range of temperature/pressure and the chemistry of the
environment
-eat a variety of food
-how to avoid or defend against predetors
