Which statement is true about stromatolites?

Stromatolites are the oldest forms of life for which there is clear fossil evidence.

Explanation:

Stromatolites are biogenic sedimentary rocks that are formed by capturing and binding sediment particles or precipitating dissolved substances as a result of the growth and metabolism of microorganisms in a body of water. They are mostly layered and often consist of very finely layered limestone. With their shell-like structure made of tubers, columns or undulating layers, some look like a cauliflower.

The oldest known fossils are mostly stromatolites, and they could therefore provide clues as to how life has developed from very simple to more complex forms.

correct answer: biotic and abiotic limitations

carrying capacity is defined as the total number of an organism who can be supported in a given area within the natural resources limit and without harming or degrading the natural, economic or the cultural environment present for the future generations.

carrying capacity is determined by the limiting factors, which are known to affect the natural resources available. it may include water, nutrients, minerals, space, light etc.
