Answer:
social facilitation
Explanation:
The concept of social facilitation was first proposed by Norman Triplett. After observing a cycling event, in which he noticed that cyclist performed better when they have others around competing with them, rather than cycling alone just against time. This led him to duct an experiment where he gave some children strings to wound fishing reel. He observed that, children wound the fishing reel faster in the presence of other children performing similar task, when compared to when perform such task alone.
This concept discovered by Norman Triplett, best illustrates the concept of social facilitation, which posits that, individuals tend to perform better in the mere presence of others or when they perform a task with others, than when performing the task alone.

Answer:
The correct answer is - reducing competition between the birds for resources.
Explanation:
In this ecosystem, the two species of birds brown creepers and nuthatches share habitat in the same tree for their food resources are insects. Brown creepers feed on resources on the bottom of the tree whereas nuthatches feed on the top of the tree.
By this, they avoid competition between these two birds for the same food resources in the same tree. The competition would be more if both have depended on the insects all over the tree.
Answer:
The correct answer is - lysosome and vacuole.
Explanation:
In the cells of animals and plants, there are many similarities and some differences as well. These similarities and differences include the organelle they both have common or specific to a particular cell.
Lysosome and the vacuoles are two organelles found in both cells; plants, and animals. In plants, there is a central vacuole large in size whereas in the animal cells the numbers are much higher and size is smaller in size. Lysosomes are also present in both animals as well as the plant cell.
Thus, the correct answer is - lysosomes and vacuole.
