Simply because they reproduce by means of internal fertilization. The embryos either develop externally inside a soft-shelled egg, or internally in the female reptile.
Sorry, not fish. But all repiles and birds lay eggs (which is sort of semi-internal) [note there are a few exceptions which have live births {i.e, the egg developes inside}] and all mammals have internal reproduction.
Yes they are.
Droplets of water are essential for bryophyte reproduction as they help in the dispersal of sperm to reach the egg for fertilization. In some bryophytes, water droplets can also aid in the dispersal of spores for reproduction. This dependency on water for reproduction is a key characteristic of bryophytes due to their need for a moist environment.
The water carries the gametes(sperm) to the other mosses for pollination.
Bryophytes, such as mosses and liverworts, need a film of water for reproduction. The sperm of bryophytes require water to swim to the egg for fertilization, as they do not have specialized structures for pollen transfer like flowering plants. Additionally, water helps in the dispersal of spores for reproduction in bryophytes.

The first organisms that did not require water for reproduction were likely plants and some types of fungi. These organisms evolved mechanisms such as pollen and spores to reproduce in dry conditions without the need for water.
they need meat water sheleter air well all this stuff becasue all living things need food, water, shelter. even reproduction to stay in existance.
The amniotic egg is the feature present in reptiles and absent in amphibians that freed reptiles from dependence on water for reproduction. The amniotic egg has protective membranes and allows reptile embryos to develop on land, reducing the need for water for reproduction.
no need for a partnerfast reproduction
Pathogens do not necessarily need light to grow, but they do require water and oxygen for growth and reproduction. Water is essential for cellular processes, and oxygen is often used in cellular respiration to generate energy.
if there was no reproduction then they wouldn't be any humans in the world
