What fossil records do you have from the Precambrian life?
very little, there are stromatolites, domed mates of microscopic algae that are aged as precambrian. No other fossils in the precambrian
How do scientists think that the first multicellular organism arose?
The oldest fossils of multicellular organism are from tiny algae that lived about 1.5 billions years ago. By 600 million years ago the first multicellular animals-jellyfish-like organisms -had evolved.
Tiny algae and animals that float in water?
Plankton :) I had the same question for science homework.
Is algae microscopic?
Certain algae is unicellular and microscopic. Multicellular algae can be microscopic, but often are not. Seaweed is an example of algae that is a single multicellular organism and not microscopic.
Where does algae grow and developed?
rocks, limestone, animals, ice, trees, water, springs, soil, trees
What are the rocks and minerals in Glacier National Park?
The National Park Service says that there is quartzite, argillite, limestone, and dolomite. Stromatolites (fossils of blue green algae) are also there. The Mountain Beltway site has some great pictures of the rocks.
What is a five letter word ending in A meaning freshwater limestone algae?
The word you are looking for is chara.It's five letters, ending in A.Chara is an algae which forms in freshwater lakes in limestone-heavy environments.
What life forms formed the earliest fossils?
Single-celled prokaryotes that are preserved in stromatolites. Stromatolites are ancient laminated rocks formed by the growth of cyanobacteria; basically they are rock-like buildups of microbial mats that form in limestone-forming environments. In combination with oncoids, stromatolites are formed by the baffling, trapping, and precipitation of particles by communities of microorganisms like cyanobacteria or red algae, etc. So in answer to your question, the oldest fossils are stromatolites, and the life forms that created those "fossils" were prokaryotic bacteria and algae like cyanobacteria.
Why do snails eat chalk?
I have never heard of water snails eating chalk, i just go to the pet store and get some algae wafers
What does algae provide animals with?
Algae provides food for some animals. For others, it can provide shelter.
What type of landforms were in the cretaceous time period?
There was a lot of chalk because a large area of the continents was covered by warm shallow seas, as a result of that there was a lot of marine limestone. You can also find chalk with many types of algae that flourished during the cretaceous period. An example of a landform would be the white cliffs of dover. There are also landforms in Sussex, the isle of Wright and East Dorset

What are animals eat algae?
plankton
Which animal feed on algae and other animals?
