Which abiotic factor limits the distribution of the ocean but does not usually limit the distribution of life on land?
water
Why does blue-green algae have trouble surviving in the deepest part of the ocean algae is a sea animal and where does it live at in the ocean and why does it stay up at the shore surface?
Blue green algae like most plant life require photosynthesis to live. Which means they need light. There is no light in the depths of the ocean bottom. The more light and nutrients, the more algae.
Where on the ocean floor can algae survive?
They can only live on the floor if there is enough light. If the algae is kelp, then it can grow long enough to reach light but still would have to be close to the light when small.
Is algae a consumer of the ocean?
yes I sw algae in ocean water. Algae grew on my ocean watered plants during a science expirement
What types of algae are in the deep ocean?
red algae red algae contain a pigment r-phycoerythrin which absorbs blue light and reflects red light. blue light can penetrate deeper parts of sea than other lights of higher wavelengths. hence we find red algae in deep sea oceans
What is the part of the open ocean that receives enough light for floating algae to carry out photosynthesis called?
Surface Zone
What affects algal growth with increasing depth in the ocean?
light, light decreases with depth, affecting photosynthesis The deeper in the ocean you go, the less sunlight is present, and the less vigorous are algae. At some particular depth, the algae can no longer support themselves, so they cannot live at the depth (or deeper).
The reason corals do not grow at great depths in the ocean is?
Because their symbiotic algae are photosynthetic and require light and warmth from the sun.
Is algae at the top of a ocean?
You don't find any algae growing much deeper than 60 feet (20 meters) because the light that is necessary for their growth is filtered out by the water. Algae, therefore, is found only near the surface.
Why red and brown algae are able to live at greater depths in the ocean?
The answer to this question is because of the efficiency of different pigments to absorb light of different wavelengths. For example, the pigment in red algae can absorb blue-green light that penetrates to greater depths.
Are Ocean currents are determined by algae?
Algae have very little to do with ocean currents, other than the fact that they ride it occasionally.
What conclusion can you reach about conditions in the parts of the ocean where marine algae may prefer to live?
it's probably the photic zone where there is light.
