Because comets are darker colored so they need light to shine on them to be seen in the dark skies of space.
Mangroves are most likely to be found in brackish water. Brackish water is more saltier than freshwater but it doesn't quite reach the level of seawater. Fun fact mangroves are called halophytes.
Answer:
fixed action pattern, key stimulus; key stimulus, fixed action pattern
Explanation:
- An innate behavior which specific to a species and is highly stereotyped is termed as a fixed action pattern.
- This behavior occurs due to a neuronal network that is hard-wired in the species and the response is said to be generated following a key stimulus.
- A key stimulus is the one that generates a fixed action pattern and this is also called a releaser.
- A key stimulus can be in the form of shape, sound, color, or a combination of these.
- In this case, the red spot is a stimulus for the chicks which causes them to peck at their parent's bill, and hence, the red spot is a key stimulus, and pecking of the chicks is a fixed action pattern.
- The parents regurgitate the food only when the chicks peck at their bills, so pecking is a key stimulus for the parents which causes them to regurgitate the food which is a fixed action pattern.
The correct answer is A - eventually a predatory species may utilize it as an energy source and its negative impact on the ecosystem will be decreased but until then, the pad trees will suffer the consequences.
