Living Organism Relationships (8.11A) 8. Which of the following is an example of a parasite-host relationship between two organisms? • Mistletoe, a flowering plant, imbeds its root system in a tree limb for food and water. The tree limb becomes weak and breaks. • Army ants travel along a forest floor and stir up different kinds of flying insects. Birds follow the ant colony and eat the flying insects. • Birds called cattle egrets search for insects in livestock fields. Livestock like cattle and horses stir up insects as they walk through the fields. • Clownfish protect themselves from predators by hiding among the tentacles of sea anemones. Clownfish eat butterflyfish, which eat sea anemones.
Abiotic & Biotic (8.11B) What are some of the consumers of each ecosystem? How would you describe the temperature in the terrestrial (land) ecosystems?

List some common abiotic and biotic factors that you would find in each of the following ecosystems: Little vegetation: cacti Very little water HOT Lizards, snakes, camels Frozen soil: small root plants like grasses Very Little water COLD Caribou, polar bears Changes w/ seasons Good vegetation: trees, shrubs… Moderate water Squirrels, owls, deer Lots of vegetation: trees, vines… Warm Lots of water & humid Monkeys, birds, snakes GRASSES, shrubs, few trees… Little water warm Rabbits, bison, gophers saltwater Algae & phytoplankton Fish, shark, whales, shellfish freshwater Algae & plankton Catfish, bass, minnows Fresh & salt water Algae & plankton Oysters, crab, young fish
Abiotic & Biotic (8.11B) • Which of these environments has the MOST biodiversity? A) a tropical rain forest B) a polar ice cap C) a desert D) a stream Biodiversity- the variety of life in a particular habitat or ecosystem.
Abiotic & Biotic (8.11B) 11. Which of the following best explains why specific physical conditions, such as temperature ranges and light, should be maintained in an ecosystem? • All organisms require the same physical conditions in order to survive. • The physical conditions of an ecosystem control the food chains in the environment. • Organisms are specifically adapted to live in the physical conditions of their ecosystem. • Organisms move to a different ecosystem if the physical conditions change in their original ecosystem.
Abiotic & Biotic (8.11B) 12. Which of the following is NOT an example of a biotic factor in an ecosystem? A) Bacteria B) Beetle C) Shrub D) Water
Abiotic & Biotic (8.11B) 13. Which is an example of competition for a biotic factor? A) groundhogs competing for places to dig burrows. B) birds competing for berries to eat. C) plants growing tall to get more sunlight than other plants. D) Snakes competing for sunny places to warm themselves.

A) Hyacinth macaws mainly eating palm-tree nuts B) Some hyacinth macaws nesting in the holes of cliffs C) Removal of 10,000 hyacinth macaws for the pet-trade business D) Hyacinth macaws spreading the manduvi tree’s seeds in their droppings
Environmental Changes and Organism Traits (8.11C) • Farmers within the hyacinth macaw’s range set yearly grass fires that often destroy the bird’s nesting trees. Which of the following best explains why this action would lead to either a short-term or long-term effect on the hyacinth macaw population? A) Short-term effect, because the hyacinth macaws can nest in cliffs B) Short-term effect, because the nesting trees will grow back quickly C) Long-term effect, because the hyacinth macaws’ nesting sites are destroyed D) Long-term effect, because yearly fires do not preven more dangerous fires
Environmental Changes and Organism Traits (8.11C) • In 1995, gray wolves were restored to Yellowstone National Park. As a result, the gray wolves began to control the park’s large elk population, which had been over-eating trees growing along the park’s streams. The recovery of the trees, in turn, has cooled the stream flows to normal temperatures. Which of the following organisms would probably benefit most from the streams’ cooler waters? A) Migrating birds that need nesting areas B) Native trout that live in the park’s water C) Trees that provide habitats for native birds D) Beavers that use willow branches to make dams
Environmental Changes and Organism Traits (8.11C) • Which of the following conclusions is best supported by the information given above? A) Polar bears will adapt to a los of Arctic sea ice and find new sources of food. B) The amount of sea ice available for polar bears has generally increased since 1978. C) The extent of Arctic sea ice each year depends on the size of the polar bear population. D) The polar bears’ survival is threatened because less sea ice makes it more difficult for them to hunt.
Environmental Changes and Organism Traits (8.11C) • The theory of natural selection explains how- A) farmers develop certain types of crop plants. B) variations appear in a species. C) environments change over time. D) useful traits spread through a population.
Environmental Changes and Organism Traits (8.11C) • What is most likely to happen if an environment changes and a species does not have variations that are helpful in the new conditions? A) Members of the species will try to change the environment. B) Members of the species will develop new adaptations. C) A new species will form from the existing species. D) The species will become extinct.
