alexgriva [62]

The complete question is :

The success of plants extending their range northward following glacial retreat is best determined by _____.

A) whether there is simultaneous migration of herbivores

B) their tolerance to shade

C) their seed dispersal rate

D) their size

Answer: The seed dispersal rate

Explanation:

The  seed dispersal can be defined as the movement of the seeds away from the parent plant. The ability of the plant to extend is completely dependent on the ability of the plant to disperse its seeds.

Plants have very limited ability, they need vectors to carry its seed from one place to another.

The biotic and abiotic vector both are involved in carrying the seeds which helps in expansion of the trees.

hence, the correct answer is option C

Please help me, is this answer correct?
dedylja [7]

Answer:

All options are correct

Explanation:

Fossils are the remains of organisms (animals and plants) preserved in a rock. Scientists (geologists & palaebiologists) have used fossils to study the diversity of organisms in the past. This is based on their preserved morphological features. For example, several species of foraminifera has been identified in the rocks. Among them, some species are present today whereas others have become extinct.

Similarly, fossils are the indicators of past climate (e.g. temperature) as well. This means, if a specific species can survive at a particular temperature, its presence suggest that particular environment. For example, corals survive in tropical waters at specific depth and sunlight. So, if we find corals fossils, the cliamte of that particular age would be roughly the similar.

In the end, fossils can also provide evidence of orogeny (mountain building) process. These are typically plants fossils which cannot move and their remains are preserved in the folding rocks.
