Virtual visitors can travel through the trails of Yellowstone National Park, as well as the Yosemite National Park. The San Diego Zoo, the Georgia Aquarium and the Monterey Bay Aquarium are offering live webcam viewings of pandas, penguins and beluga whales. With the help of Google Earth, users can take a tour of some of Hawaii’s beautiful landmarks, such as Hawaiʻi Volcanoes National Park and Waikiki Beach.

Organisms interact with other organisms as well as nonliving things (such as air and water).
Both plants and animals can compete for resources.
Animals can be predators AND prey.
Soil has nonliving parts like dirt or rocks along with living things like worms, bacteria, tree roots, etc. The same is true for bodies of water which have both the nonliving part (water) and living parts such as frogs, bacteria, fish, clams, etc.
Organisms interact with both living and nonliving things to survive in their ecosystems. Living things can be studied at increasing levels of interaction: the response of a single organism, a population of similar organisms, or a community of different organisms that live together in an ecosystem.
Plants interact with living things such as animals and other plants in complex ways and also require nonliving things such as carbon dioxide, water, and sunlight. Life within an ecosystem is interdependent.
Plants interact with living things such as animals and other plants in complex ways and also require nonliving things such as carbon dioxide, water, and sunlight. Plants need nonliving things, such as carbon dioxide in the air, sunlight from above, and water brought up by their roots to survive. Through the process of photosynthesis, plants, as producers, change sunlight, carbon dioxide (produced by animals), and water to make glucose or plant food. As a by-product, plants release oxygen, which animals need.
Animals depend on other living things, such as plants and other animals, and nonliving things, such as air and water, to survive.
Animals that depend on different kinds of living things for food are grouped into herbivores (animals that eat plants), carnivores (animals that eat other animals), omnivores (animals that eat both plants and animals), and decomposers (bacteria and fungi that break down dead organisms for food). Animals that hunt other animals are called predators. Animals that are hunted are called prey.
