These terms are fairly intuitive. External means outside. Internal means inside. Fertilization occurs when the male gamete (sperm) meets the female gamete (egg).
External fertilization is fertilization that occurs outside the body, whereas internal fertilization is fertilization that occurs inside the body (usually the body of the female).
The lion uses the same fertilisation as the human does.
dog
An elephant uses the internal fertilization as the male elephant mounts the female
A dragonfly uses internal fertilization. This means that fertilization happens inside the female body and requires copulation in order to happen.
It is said to be Alive
almost every living organism uses homeostasis to do this
An organism that uses energy to maintain stable internal conditions despite changes in its external environment is known as a homeostatic organism. Through processes like thermoregulation and osmoregulation, these organisms can adjust their internal conditions to ensure survival. Examples include mammals regulating body temperature and fish adjusting salt levels in their bodies.
A human, any organism that can control its inner environment against the outside environment, unlike the fish.
The cat, like all mammals uses sexual reproduction, with internal fertilization. The foetuses develop inside the mother and the young are born alive.
Heterotrophs are organisms that uses organic compound as its source of food whereas detritivores are organism that uses organic waste as its source of food.
Sexual reproduction is the mode of reproduction for cows. They use internal fertilization which means the egg is fertilized inside the cow.
Whale has internal fertilization,because they are mammals like human. ^_^
