Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Answer:
B. Do not need much water, so they prefer soil that drains the water.
Explanation:
Sandy soil is one of the three basic soil types we have in nature (the others being loamy soil and clayey soil). One of the properties of the Sandy soil is its high water draining ability i.e. it has a low water holding capacity. This draining characteristics is due to the large pores that Sandy soils possess.
According to this question, three plants namely: yarrow, bearded iris, and sea oats grow best in sandy soil. This indirectly means that these plants mentioned do not need much water for their growth since they grow best in a soil that drains water efficiently.

True
Explanation:
Pioneer organisms are the first organisms that reoccupy a region that was destroyed by a disaster like flood, forest fire, volcanic eruptions, etc. These pioneer species can grow in the habitat that is barren and is not suitable for the growth and survival of other species.
Some of the pioneer species are lichens and algae. Pioneer species like lichens help in the formation of soil from breakdown or rocks which allow the formation of a suitable environment for the ecological succession of other species like mosses, algae, and other small plants. Therefore the statement is true.
