Answer:
The correct answer would be C) It increases survival for cuckoos, but decreases survival of the other birds.
The host chicks often face lots of competition from the cuckoo chicks in terms of food as well as space. It makes it difficult for the host chicks to survive.
It has also been found that cuckoo chicks beg to be fed more intensely due to which host chick die due to starvation.
In addition, in some species of cuckoo, cuckoo chicks remove host eggs from the nest within few days of hatching.
Warm-blooded creatures, like mammals and birds, try to keep the inside of their bodies at a constant temperature. They do this by generating their own heat when they are in a cooler environment, and by cooling themselves when they are in a hotter environment. To generate heat, warm-blooded animals convert the food that they eat into energy. They have to eat a lot of food, compared with cold-blooded animals, to maintain a constant body temperature. Only a small amount of the food that a warm-blooded animal eats is converted into body mass. The rest is used to fuel a constant body temperature.
Wrong carbon dioxide goes into the plants leaves and comes out as fresh air
Certain elements are required in large quantities, and others are required in small amounts by the body, but both are essential for the survival of the cells. The cells which are required in large amounts are called as macronutrients, while the ones required in small quantities are called as micronutrients, or trace elements.
Hence, the answer is trace elements or micronutrients.
