Answer:
<u>Oxbow lake is formed when a bend in a river is cut off to form a lake.</u>
Explanation:
- <u>OPTON A - It is formed as lakes grow larger due to erosion and begins to look like an ox. </u>
This statement is incorrect , as the shape of the oxbow lake is not like an ox , it is a <u>horse-shoe shaped lake .</u>
- <u>OPTION B - It is formed when a bend in a river is cut off to form a lake.</u>
This statement is correct , as An oxbow lake is a U-shaped lake that forms to create a free-standing body of water when a large meander of a river is cut off.
- <u>OPTION C - It is formed when a delta grows large enough to cut off a river to form a lake. </u>
This statement is also wrong, as a<u> river delta</u> is specified by this statement.
- <u>OPTION D - It is formed when a dam stops the flow of a river and creates a lake.</u>
This statement is also false, since the creation of a<u> reservoir</u> is established by this statement.
<u>FORMATION OF OXBOW LAKE -</u>:The neck of the meander gets narrower and narrower progressively. The curve gradually grows so close that the river slices through the neck of the meander to take a new, straighter path. Sediment locks the end of the old loop over time. This leaves a region of water that is different, called an oxbow lake.
Hence , <u>the correct option is B.</u>

Answer: Competition
Explanation:
An ecological niche is the place of a given organism within its ecosystem. A niche consist of limited resources such as food, shelter, space, light, desired temperatures, moisture for the organism to survive.
Two or more species of organisms may have similar basic needs and occupy the same niche. When different species population occupy the same niche, they compete for these limited natural resources.
Competition occurs when 2 or more organisms or populations in a community rely or need similar limiting resources.
