Sediment or sedimentation is the term used for solid organic matter transported by wind, water or glacial erosion. Usually, Sediment is formed by weathering or rock. In time, this sediments will be accumulated and formed in a place in which it will stay.
The statement that is a well-written hypothesis about DDT and its effects on the environment is as follows: If DDT levels in the environment increase, then the number of predatory birds will decrease (option B).
<h3>What is an hypothesis?</h3>
Hypothesis is a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further observation, investigation or experimentation.
Hypothesis is widely regarded as an educated guess because it predicts the outcome of an experiment and can be tested to either be true or false.
A hypothesis is usually written as an IF, THEN statement.
Therefore, the statement that is a well-written hypothesis about DDT and its effects on the environment is as follows: If DDT levels in the environment increase, then the number of predatory birds will decrease.

Answer:
In winter, the forest is extremely cold. The roots of the evergreen plants are unable to access water. The needle-like structure of these trees minimizes water loss from transpiration. The needles are also dark in color. The color allows them to absorb maximum sunlight for photosynthesis. Even with little food, the animals in the biome can access food from these trees. Squirrels can eat the seeds from the pinecones. Crossbill birds have special beaks that allow them to access the seeds. Moose eat sappy twigs. They’ve also adapted to build fat reserves to help them survive the harsh winter. Some animals hibernate, and others migrate to warmer places to survive the winter. During summer, the long days allow abundant photosynthesis. So, there’s increased plant growth accompanied by increased insect activity. Trees with seasonal leaves develop new leaves. Birds that had migrated return during the summer, when food is readily available. The plants and animals work as a system to obtain an adequate food supply throughout the year.
