Answer:
The increase in the abundance of plants typically wild weeds acquire the entire space occupied by the water body and this leads to the transformation of the aquatic ecosystem into terrestrial or land ecosystem.
Explanation:
Instead of photosynthesis, some of the autotrophs can survive without sunlight as an initial energy source because they use a process called chemosynthesis in which they harness chemical energy released from sulfur vents under the ocean, rather than from the sun.
<h3>What is an Ecosystem?</h3>
An ecosystem may be defined as the place or area where members of different species live together and interact with one another for the purpose of food, shelter, and space.
The process of chemosynthesis does not utilize energy from the sun to synthesize food. Rather, it makes food utilizing energy from chemical reactions, frequently incorporating hydrogen sulfide or methane with oxygen. The autotrophs who perform this process are known as chemoautotrophs.
Therefore, it is well described above.

I believe the purpose of the horns in the monsters is to make them look scary for work and thus appear charming to the monster sexes. Assuming that the monsters mate sexually, the selection of the horn numbers will depend on the whether more numbers of it make one look beautiful or whether it incurs any work related advantage. A small monster colony has a large amount of monsters that have an abnormal amount of horns. This indicates that the abnormal number of horns are preferred over fewer horns as they carry a certain advantage of having a scarier look.
A Scientist would consider the color and the width of tree rings give clues about the past climatic conditions of a place.
<u>Explanation:</u>
Trees are quite sensitive to local climatic conditions like rain, temperature, etc. That is why they tend to be useful for weather experts to judge the climate variations. There are many clues seen in the rings of the trees that are helpful in studying the local climate.
Some of the clues are obtained by
- Seeing the patterns and width of the rings
- Seeing the density and composition of the rings
- Smelling the odor of the wood.
- Location
The concentric rings tell about the age of the tree and the weather conditions during its life period. The light - colored rings tells that the tree has grown in the spring and early summer season whereas the dark rings tell that the tree has grown in late summer and during fall.
Moreover, the rings get wider in warm, wet years and get thinner in cold and dry seasons. If the tree has experienced harsh conditions like drought, etc., it will have a hindered growth.
