Why is it important that animals that have external fertalisation produce a lot of eggs?

Take any animal that has external fertilisation. Each of these eggs has only a small chance a) being fertilised in the first place and b) actually surviving to hatch, so to speak. So many eggs are laid at once to increase the chance that there will be a decent amount of offsping.
Also bear in mind that alot of the offspring won't make it past the early stages of life due to predators etc.

Why are penguins important?
Penguins are part of the Antarctic food chain. We need to preserve animals so that other animals survive and don't over produce.
Why does organisms that use internal fertilization produces less offspring than the ones that use external fertilization?
Because internal fertilization requires a womb and placenta to protect and nourish the growing embryos - which limits the number of offspring the mother can produce. Laying eggs outside the body means the female can potentially produce many more off-spring, and thus vastly increase the chances of the species survival.
Why do animals produce identical offspring and humans dont?
Animals don't always produce identical offspring. Like cats for an example.
Do animals produce diploid spores?
Spores are produced during sporogenesis, which is found specifically in plants, algae and fungi. No animals currently produce spores as a method of reproduction.
Why animals need plants to produce oxygen and why plants don't need animals to produce carbon dioxide?
because when the sun shines we are shining together , told you we will be til forever .....
What adaptations in aquatic animals help ensure that external fertilization will occur?
produce more eggs
How animals important to plants?
Plants are very important to animals because they produce the food that herbivore animals, such as cows, sheep, der, etc. eat.
What is the diffenence from warm blooded and cold blooded animals?
Warm-blooded animals produce warmth through homeostasis in their body. Cold-blooded animals gather heat through external means.
Why are green leaves necessary for animals to survive?
They are important because they produce oxygen through photosynthesis with carbon dioxide, which animals breathe out.
Are exothermic animals cold blooded?
Yes, they are. The opposite exothermic animals are "endotherms." Endotherms can produce enough heat from chemical reactions within the body to maintain a constant body temperature, while exothermic animals depend on the external temperature.
What is the scientific name for animals that can produce their own body heat?
Endotherms or homeotherms are animals that can produce their own body heat through internal processes such as metabolism. They are able to regulate their body temperature independently of the external environment.
Why are farmers so important?
They grow plants and animals which produce food for many many humans to eat.
Why are penguins important?
Penguins are part of the Antarctic food chain. We need to preserve animals so that other animals survive and don't over produce.
What do trees produce that is so important to your survival?
Medicine,oxygen,feeds hervivore animals.. We eat animals and other animal feed on them a cycle of life
Do all animals produce food?
No. Animals do not produce food, they consume it.
How do cold blooded animals breathe?
From an external heat source like the sun.
Why is carbon important to animals?
without carbon oxygen cannot be produce thus makin no oxygen will result in major losses of lives
