estuaries
Answers
Explanation:
7 An estuary is a partially enclosed, coastal water body where freshwater from rivers and streams mixes with salt water from the ocean
8 An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents. Abiotic and biotic factors work together to create a unique ecosystem.
9 Tides affect marine ecosystems by influencing the kinds of plants and animals that thrive in what is known as the intertidal zone—the area between high and low tide.
10. The living components of the environment are known as biotic factors. Biotic factors include plants, animals, and micro-organisms. The non-living components of the environment are known as abiotic factors. Abiotic factors include things such as rocks,water,soil,light,rocks etc...
11. An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.
12. herbivore. An herbivore is an organism that feeds mostly on plants. Herbivores range in size from tiny insects such as aphids to large, lumbering elephants.
13. carnivore. A carnivore is an organism that eats mostly meat, or the flesh of animals. Sometimes carnivores are called predators.
14. Sheep, deer, giraffes, camels, and cattle are all ruminants. Some herbivores eat any plant matter they can find. Elephants, for example, eat bark, leaves, small branches, roots, grasses, and fruit. Black rhinoceroses also eat a variety of fruits, branches, and leaves.
15. eats plants and animals. The term stems from the Latin words omnis, meaning “all or everything,” and vorare, meaning “to devour or eat.” Omnivores play an important part of the food chain, a sequence of organisms that produce energy and nutrients for other organisms.
16. In ecology, a food chain is a series of organisms that eat one another (so that energy and nutrients flow from one to the next). For example, if you had a hamburger for lunch, you might be part of a food chain that looks like: grass → cow → human.
17. dead, organic materials, detritivores—like millipedes, earthworms, and termites—eat dead organisms and wastes.
18. A food web is a diagram of feeding relationships that includes multiple intersecting food chains. Energy is passed up the food chain from one trophic level to the next but a lot of it is lost along the way.
19. An animal that eats the leaves and shoots of trees is called a folivore. Pandas, which feed almost exclusively on bamboo, are folivores. Termites are insects that feed mostly on wood. Wood-eaters are called xylophages.
20. Herbivores
An herbivore is an organism that eats mainly plants and other producers.
