1. Explain why climate modelers can never be certain of their predictions:

Climate modelers can never be certain due to the complexity and number of factors involved such as complex natural systems, a lack of long term accurate data, uncertainty about the way human and natural activity influence climate and climate models often need to be simplified in order to get them to work.

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.

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.
