Apply the concepts: weathering, erosion, and deposition; How do plants and animals change the Earth's surface?
(AGHHHH it's DUE TODAY)
Answer:
Animals make changes to the environment by eating.Animals Cause Erosion and Weathering
Explanation:
Animals cause erosion and weathering. For example, you might see snails along rocky ocean shorelines. Some of these snails eat algae that grow under the surface of the rock. They use their hard mouth parts to scrape away the surface of the rock to eat the algae. this constant scraping of many thousands of snails weathers and erodes the rock over time.
Animals cause erosion in other ways too. When too many animals live in one place, they tend to eat and trample all the plants Without the plants to protect the soil, it is much more likely to be eroded by wind and water. Other animals change Earth's surface by burrowing into it and moving material. Too many animals in one place can destroy most of the plants, leading to faster erosion. photosynthetic life altered the atmosphere through the production of oxygen, which in turn increased weathering rates and allowed for the evolution of animal life; and how microbial life on land increased the formation of soil, which in turn allowed for the evolution of land plants.

Why do scientists find it helpful to create models of interactions in an ecosystem?
Answer:
Models enable researchers to simulate large-scale experiments that would be too costly or unethical to perform on a real ecosystem. … Ecosystem models have applications in a wide variety of disciplines, such as natural resource management, ecotoxicology and environmental health, agriculture, and wildlife conservation.

“Who could do justice to my feelings at this moment [of freedom]? Not conquering heroes, themselves, in the midst of a triumph. Not the tender mother who has just regained her long-lost infant, and presses it to her heart. Not the weary hungry mariner, at the sight of the desired friendly port. Not the lover, when he once more embraces his beloved . . . after she had been [taken] from his arms! All within my breast was tumult, wildness, and delirium! My feet scarcely touched the ground, for they were winged with joy, and, like Elijah, as he rose to Heaven, they ‘were with lightning sped as I went on.’”
