Interspecific competition can occur between two different species competing for the same resource in an ecosystem. So for this particular bug population, there may be another insect species that competes for the same food source or another resource, such as material or space for breeding habitat. This can lead to selective pressure, and may result in the different species evolving a more specific diet or inhabiting a niche environment.
Answer:
3. detection and response to stimuli
Explanation:
According to the given information, the thermoreceptors present in the skin layers of dogs and cats sense the change in the temperature of surroundings. When the temperature is reduced during a cold day, the sensory information about the same is sent to the central nervous system which in turn sends the motor information to the related muscles and glands.
One such response towards the lower temperature conditions is an expansion of their skin coat layers to insulate the underlying tissues from the cold surroundings. The same response (expansion of skin coat) is produced when these animals sense the danger of the presence of large predators around them.
Answer:
After 14 years the population of these birds reached to 300.
Explanation:
The main reason for the extinction or decrease in population of these birds are over hunting or the introduction of invasive species in the ecosystem. Due to over hunting by humans many beneficial species are extinct which causes imbalance in the ecosystem which can't be corrected. These population should be increased by providing a suitable environment to these birds.
