What could happen to the reproductive process of mosses during a drought? The flagellated sperm would not be able to swim to the
Wittaler [7]
The answer is <span>The flagellated sperm would not be able to swim to the eggs for fertilization.

</span><span>Their life cycle of mosses has alternation of generation - a haploid gametophyte and a diploid sporophyte. Gametophyte produces haploid gametes which fuse to form a diploid zygote. The zygote grows into diploid sporophyte which produces haploid spores. The spores grow into gametophyte and the cycle begins again.
</span>Mosses require water for reproduction. Before fertilization, the sperm swims to an egg through the water. Therefore, mosses require water for successful fertilization. In drought periods, without water, the sperm cell could not swim to the egg cell.

Explain why cold-blooded organisms like reptiles have a higher rate of secondary productivity than warm-blooded mammals.
PIT_PIT [208]
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.
