Your answer is A ; weathering and erosion
Explanation:
On the surface weathering and erosion break down igneous rocks into pebbles,sand and mud ,creating sediments which accumulates in basins on the Earth's surface
Primary succession will occur in (D) a landscape without vegetation or soil. This type of succession occurs in areas where the existing landscape may at one point been destroyed, such as a lava flow area that has destroyed all existing life and soil properties during the volcanic eruption.
Answer:
Explanation:
The evolutionary tree is composed of,
- Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches ⇒ Elephant species X, Y, Z
- Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor ⇒ The red spot in the graph shows the location o the most recent ancestor between species X and Y
- Root → This is the older common ancestor that all lineages share. The first one in the tree ⇒ The blue spot in the graph show the oldest common ancestor shared by the three species
Two or more lineages are more related to each other if they share a recent common ancestor -In this example, X and Y are more related to each other-. This means that they all diverge from the same node.
Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
Answer: Predation
Explanation:
Predation is the biological interaction between two organisms whereby one benefits by feeding on the other. The organism that kills and eats another is known as Predator e.g lion, I while the other that is eaten is known as prey, e.g rabbit
