1. some of the circumstances that are often faced by terrestrial biomes.

29. In some parts of the world, forests are being cut down and burned to clear land for new homes and new farmland. A negative effect of these activities might be A. an increase in edge effect B. a decrease in the average temperature of the atmosphere C. an increase in biodiversity of the deforested areas 30. Which action by humans could improve the quality of the air? A. building homes that use only oil (fossil fuel) furnaces for heat B. buying cars that get more miles per gallon of gasoline C. increasing the number of coal-burning power plants that generate electricity D. cutting down forests to clear land for factories 31. Which action shows an increased understanding and concern by humans for nature? A. importing organisms that could become invasive to try stabilizing existing ecosystems B. getting rid of pollution control laws for industries that promote technology C. removing natural resources at a rate equal to the needs humans D. putting laws in place that regulate the number…

8. Various studies in terrestrial and aquatic habitats (e.g. stream invertebrates) suggest that species richness is highest in communities where disturbances are (A) very frequent and severe, (B) very frequent and of moderate intensity, (C) very rare and severe, (D) of intermediate frequency and moderate intensity, (E) very rare and mild.

40. Why is biodiversity important?   Increased biodiversity can lead to improved and functioning ecosystem services. All of the choices are true. A loss of biodiversity can be bad for humans, either directly or indirectly. Increased biodiversity can make a habitat more stable.

1. Distinguish between Primary and Secondary succession. Which of these processes would you expect to proceed more rapidly?

1. Identify the hot terrestrial biome (20°C to 35°C), with very high rainfall, and the highest diversity of plant and animal species (like Andagoya, Columbia, in South America, at 5° North latitude). A. the tropical rain forest B. the temperate seasonal forest C. the tropical desert D. the boreal grassland (plains) E. the tundra desert

5. The native flora garden features ecosystems that can be found within how many miles of New York City? ot whu, is it imnortant that t he plants used in the ovhihi

3. Construct an Explanation Provide evidence to support the claim that secondary succession tends to occur faster than primary succession. NOTEBOOK

4. This photograph was taken in 2004, 24 years after Mount Saint Helens erupted. Compare and contrast this photo with the previous three. What changes do you see in the biotic and abiotic factors? Does anything surprise you about this series of photographs? What type of succession is taking place?
