What fertilization is most common among terrestrial animals?
Yes, internal fertilization is a reproductive strategy used by virtually all terrestrial animals. In aquatic environments, external fertilization is much more common.
Why do you think there is a basic difference between the kinds of fertilization most common in aquatic and terrestrial animals?
the process of fertilization involves fusion of egg/ova and spermatozoa. the two cells are also called gametes. for their meeting aqueous medium is required. in land animals out side environment is dry therefore fertilization on land is not possible while as genital tract provides similar aqueous atmosphere where spermatozoon swim to reach the egg.
what is the difference between an aquatic and a terrestrial ecosystem?
An aquatic ecosystem is based on water, and a terrestrial ecosystem is based on land.
What is the difference between terrestrial animals getting oxygen and aquatic animals?
Amphibians can live both on land and water
Where do most animals that have external fertilization live?
They are aquatic.
How do animals fertilize plants?
Internal fertilization and external fertilization. Internal fertilisation means fertilize the egg inside the female's body. External fertilization is fertilize the egg after the female had lay it out. All mammals including platypus and spiny anteater do internal fertilization.
Are animals aquatic or terrestrial?
Both. If your referring to mammals the answer is still both.
What is the difference between aguatic and terriestal?
Aquatic refers to things related to water or living in water, while terrestrial refers to things related to land or living on land. Aquatic organisms are adapted to an aquatic environment, while terrestrial organisms are adapted to living on land.
Do some terrestrial animals respire with gills?
No, terrestrial animals do not respire with gills. Gills are respiratory organs found in aquatic animals that extract oxygen from water. Terrestrial animals typically respire using lungs or tracheal systems to extract oxygen from the air.
Why breathing rate of aquatic organisms is faster than the terrestrial animals?
The breathing rate of aquatic animals is faster than that of terrestrial animals because the amount of dissolved oxygen in the water in much less than the amount outside, so they have to breathe more in order to get more oxygen
Aquatic is to water as what is to land?
Terrestrial
What adaptations in aquatic animals help ensure that external fertilization will occur?
produce more eggs
