In what Era did the first land dwelling organisms appear?
the paleozoic era
What is the difference between terrestrial biome and aquatic biome?
Differences between Terrestrial and Aquatic systemsbecause aquatic environments are so rich in nutrients they support more live than equivalent terrestrial ecosystems. The small drifting photosynthetic organisms of the oceans, referred to collectively as phytoplankton are regarded as the major photosynthesizers, or primary producers, of the earth,aquatic environments are much more stable than terrestrial environments, with smaller fluctuations in temperature and other variables,aquatic organisms are seldom exposed to desiccationwhile terrestrial organisms are often exposed to desiccation and are usually relatively resistant to drying out,oxygen (because there is very much less present) is sometimes a limiting factor an aquatic habitats but this is seldom the case in terrestrial habitats,light can be a limiting factor in some aquatic habitats, but in most terrestrial environments there is hardly ever a a shortage of light,terrestrial animals are influenced far more by gravity, while water supports aquatic organisms.
What group contains organisms that are the least similar?
Protozoans protozoans is not one of the picks.these are the picks:bacteria,land plants,aquatic dinosaurs or invertebrate sea animals.
Where is the first living organism on earth in air or land water atmosphere?
The first living organisms on earth were a type of aquatic photosynthetic bacteria called cyanobacteria (blue-green algae). These organisms formed structures called stromatolites. These organisms did not become extinct and still exist in both salt and fresh water environments.
Organisms with tails and legs and with lifestyles that are both aquatic and terrestrial are found in order?
Caudata, which includes the salamanders and newts. These creatures have both tails and legs, and are amphibians, meaning they can live both on land and under water.
Fossils from this era contain simple aquatic organisms with no evidence of life on land?
The answer is Proterozoic.
In what Era did the first land dwelling organisms appear?
the paleozoic era
What problems do land organisms face that aquatic organsims do not?
Hello

increasing abundance of food sources on land
What factors determine where an organism lives?
Biotic factors help determine where specific organisms live
What land-dwelling kingdom's members absorb food from living and non-living organisms?
fungi
Are mammals and reptiles similar?
They have some similarities. Both reptiles and mammals are primarily land-dwelling vertebrates, though some species are aquatic.
Do organisms in an aquatic environment need different things than organisms in land environments?
no all organisms need the same things like water food oxygen and a home
What is the aquatic land form?
the aquatic is wetlands
Is the fastest land dwelling creature the cheetah?
Yes it is.
Is a toucan land or aquatic?
Land
What type of rock forms a fossil?
sedimentary rock -sedimentary rock because organisms die on land or on the bottom of a body of water and the sediments cover it and harden to form fossils. -also, limestone can form fossils.
