Hmm... after some long thinking about this I would have to go with land. After land has been frozen, it thaws (<span>become liquid or soft as a result of warming.) Heat cannot "thaw" because it is apart of air. Water cannot "thaw" because it is already a liquid. Makes sense? I hope this helps! P.S. (A brainliest wouldn't hurt) ;)</span>
The interrelationship between the Elodea plant and paramecia in a pond system is mutualism.
The pond system is a type of an artificial aquatic system that contains organisms (plants and animals) that are regularly maintain.
The Interrelationship between organisms which can occur in an ecosystem include:
- competition,
- predation,
- commensalism,
- mutualism and
- parasitism.
Mutualism occurs when two organisms of different species benefits from each other.
The Elodea plant purifies the water through photosynthesis and provides habitat for the paramecia
The paramecia in turn generates carbondioxide through its body surface which is a key element used for photosynthesis by the Elodea plant.

Answer:
c. Directional selection
Explanation:
There are three types of selection: stabilizing, directional and disruptive. Currently seed cracker finches show disruptive selection with respect to bills. In disruptive selection two extreme phenotypes are preferred in population over the mean phenotype. Here either, small or large bills are beneficial for birds so it is an example of disruptive selection.
If due to some climatic change all seeds would become hard, it would be more beneficial for birds to have large bills. Slowly nature will select for birds with large bills rather than birds with small bills. The selection now will shift to directional selection since only one of the extreme phenotypes is being favoured.
Animals will migrate to other regions in search of food
The new species will evolve to survive in the deforested land
It's highly unlikely the animals will immediately adapt and the number of trees is decreasing because they're being cut down. Unless the question explicitly states that trees are being planted to replace those being lost.
