More elephant seals and peguins would be eating (killing) the squids. Also it might not realy change at all because the squid has much more krill and small animals to eat.
Ans. (D). community.
In an ecosystem, a community can be defined as a association or group of organisms of two or more species that occupy the same region, in a particular time. For example, grasses, herbivores (such as deer), and carnivores (such as lion represent a community in a grassland ecosystem that affect each other.
As earthworms and robins belong to two different species, they will represent a community in a beech forest ecosystem.
Thus, the correct answer is option (D).
Answer:
D
Explanation:
The correct answer would be that the origin of all cells can be traced to previous or pre-existing cells.
According to the cell theory which is made up of three parts;
- <em>The cell represents the basic unit of all life.</em>
- <em>All living organisms are made up of cells.</em>
- <em>Cells do not arise spontaneously, but only from pre-existing cells.</em>
Hence, the discovery that the origin of all cells is traceable to previously existing cells supports the latter part of the cell theory.
The correct option is, therefore, D.
Answer:
Option (a), (b), (c) and (d).
Explanation:
Cytokinesis may be defined as the process by which the cytoplasm of the cell is divided into the two daughter cell. This process is quite similar to the process of binary fission of prokaryotes.
The cytokinesis follows after the telophase stage. The cytoplasm with the organelles are divided into the daughter cells from the parent cell. This process is proceeded with the formation of the cleavge furrow in the animals ans divides into daughter cells.
Thus, the correct answer is option (a), (b), (c) and (d).
