All organisms must have water for survival. If a drought causes the water in an ecosystem to become scarce, the organisms in this ecosystem will not have it as much water accessible to them.

a decrease in the water available to an organism for cellular processes will most likely result in

A. a decrease in optimal temperature ranges
B. an increase in activity level
C. an increase in metabolic activity
D. a decrease in metabolic activity

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

e) all of the above

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.

idk im sorry.

d. planting trees

the trees take in carbon to make oxygen.
