It’s basically asking like what is changing with each of the samples and you have to write what type of change, which I’m guessing is physical or chemical changes.
The sun formed from the compression of a cloud of gas and space dust.
so C, I just had this question on a science test, what a coincidence
Answer:
Economic Benefits of Land Conservation
Economic Benefits of Parks
Economic Benefits of Trails
Economic Benefits of Smart Growth and Costs of Sprawl
Explanation:
Maintaining biodiversity is essential for organic waste disposal, soil formation, biological nitrogen fixation, crop and livestock genetics, biological pest control, plant pollination, and pharmaceuticals. Plants and microbes help to degrade chemical pollutants and organic wastes and cycle nutrients through the ecosystem. For example:
Pollinators, including bees and butterflies, provide significant environmental and economic benefits to agricultural and natural ecosystems, including adding diversity and productivity to food crops. As many as one-third of the world’s food production relies directly or indirectly on insect pollination. About 130 of the crops gown in the United States are insect pollinated. Habitat fragmentation and loss adversely affects pollinator food sources, nesting sites, and mating sites, causing precipitous declines in the populations of wild pollinators.
