List two examples of a herbivore: cows, deer, zebra 2. If a snake eats a mouse that eats grass, the snake is a second-level consumer. 3. The many overlapping food chains in an ecosystem make up a(n) food web. 4. A diagram that shows the amount of energy that moves from one feeding level to another in a food web is called a(n) energy pyramid. 5. Consumers that eat both plants and animals are called omnivores. 6. The first organism in a food chain is always a producer. 7. Dandelions, roof rats, and other organisms that were brought by humans from one part of the world to another and then became pests, are examples of invasive species. 8. In an energy pyramid, the level which has the most available energy is the producer level. 9. Vultures, which feed on the bodies of dead and rotting organisms, are scavengers. 10. An organism that can make its own food is called a producer. 11. Yellowstone National Park, the world’s first national park, is an example of habitat preservation. 12. In the last few centuries, the number of species becoming extinct on Earth has increased/ decreased dramatically. 13. The number of different species in an area is referred to as its biodiversity. 14. The loss of a natural habitat is called habitat destruction. 15. The Nene goose in Hawaii is endangered because of the introduction of rats, a(n) invasive species. 16. The largest population that an environment can support is called its carrying capacity. 17. Three factors that affect an area’s biodiversity: area, climate, diversity of niches. 18. A species that influences the survival of many other species in an ecosystem is called a(n) keystone species. 19. Two examples of a predator adaptation: cheetah speed, shark's jaws 20. Laws can help protect endangered species by prohibiting products made from the species. 21. An example of a biotic factor in the prairie ecosystem is grass. 22. When a jellyfish paralyzes a tiny fish with its poisonous tentacles, the fish is the prey. 23. The behaviors and physical characteristics of species that allow them to live successfully in their environment are called adaptations. 24. Factors that can become limiting in an ecosystem include food, water, shelter, space and weather. 25. An organism’s particular role in its habitat, or how it makes its living, is called its niche. 26. The struggle between organisms to survive in a habitat with limited resources is called competition. 27. An early winter frost preventing further growth in a tomato garden is an example of a limiting factor. 28. Fungi that decompose dead organisms return important nutrients to the soil. 29. An interaction in which one organism kills and eats another is predation. 30. Wildlife tourism, or “ecotourism,” is an example of the economic value of biodiversity. 31. If all members of a species disappear from Earth, the species is said to be extinct. 32. The mating of California condors in zoos is an example of captive breeding.
