Answer 2

• External fertilization happens when a female stores eggs outside her body and the male deliveries sperm onto them.
• External fertilization normally requires a watery climate and is utilized by most fish and creatures of land and water.
• External fertilisation allows the zygote to feed on the nutrient-rich yolk that was already present in the egg before fertilisation. It can feed the zygote until it hatches because it is self-sufficient.
