Distinguish between the following:
(a) Hibernation and Aestivation.
(b) Ectotherms and Endotherms
Solution and Explanation
(a) Hibernation and Aestivation
| Hibernation | Aestivation | ||
| 1. | Hibernation is a state of reduced activity in some organisms to escape cold winter conditions. | 1. | Aestivation is a state of reduced activity in some organisms to escape desiccation due to heat in summers. |
| 2. | Bears and squirrels inhabiting cold regions are examples of animals that hibernate during winters. | 2. | Fishes and snails are examples of organisms aestivating during summers. |
(b) Ectotherms and Endotherms
| Ectotherms | Endotherms | ||
| 1. | Ectotherms are cold blooded animals. Their temperature varies with their surroundings. | 1. | Endotherms are warm blooded animals. They maintain a constant body temperature. |
| 2. | Fishes amphibians and reptiles are ectothermal animals. | 2. | Birds and mammals are endothermal animals. |

Population Interactions
Population interaction is generally between two different species populations.“Population interaction is the interaction between different populations. It refers to the effects that the organisms in a community have on one another.”
An ecosystem is a geographic area wherein plants, animals, and many other organisms, alongwith weather and landscape, work together to form a bubble of life.
Types of Population Interactions:
Interactions can be beneficial or neutral or detrimental. Accordingly, there are six types of population interaction.
The different ways populations interact with each other can be summarized under the following headings.
- Competition
- Predation
- Herbivory
- Mutualism
- Commensalism
- Parasitism
