Why do photosynthetic organisms live on or near the surface of aquatic ecosystems?

Photosynthetic means that they synthesize their own food from the light of the sun. Therefore, they have to live near the water's surface so that the light can reach them for photosynthesis.

What is the ultimate source of energy for nearly all surface terrestrial and shallow water ecosystems?
The sun.
What do continental and oceanic plates cause?
Continental and oceanic plates give our planet a solid surface upon which we can have ecosystems habitable by people and other organisms. Without the plates, we are left with the mantle, which is composed of hot, melted rock, upon which nothing could live.
The layer where organisms can exist on the surface of the earth?
Biosphere
What Distribution of different organisms over the earth surface?
evidence for evolution
What is on the surface of earth?
On the Earth there is life basically such as organisms like us and animals.
What are the photosynthetic organisms found near the surface of the ocean called?
Phytoplankton
What photosynthetic organisms found at the surface of the ocean?
The answer to your question is phytoplankton
The population of small photosynthetic organisms found near the surface of the ocean?
Phytoplankton
What are the small photosynthetic organisms found near the surface of the ocean called?
Phytoplankton
Small photosynthetic organisms living near the ocean surface?
plytoplankton
Are the population of small photosynthetic organism found near the surface of the ocean?
Yes, the photosynthetic organisms are regulated near the surface according to surchams theory, and the microorganisms innterrelated neighbours are found near the focus of the ocean on the oceanic boundary.

What is the connection between organisms in a stream and the dissolved oxygen level?
Organisms in streams need oxygen to live when lacking dissolved oxygen it will kill these organisms. edit: unless the organisms in the stream are photosynthetic, in which case they will increase the oxygen levels. however, by far, most organisms in a stream are not photosynthetic and oxygenation occurs solely through aeration and surface area dissolving from the air. so, to answer the question, organisms (most organisms which aren't plant-based photosynthetic organisms) decrease the amount of oxygen in a stream. edit: a flowing stream has turbulence which helps aerate the water, increasing dissolved oxygen. In contrast, stagnant water tends to be low in dissolved oxygen, except near the surface. Multicellular animals (like fish) need a good supply of dissolved oxygen to thrive.
What layer are organism can exist on the surface of the earth?
All living organisms live on the crust of the earth. This is called the biosphere and contains all the ecosystems in the world.
How can a body of water can be depleted of its oxygen?
Water can be depleted of it's oxygen by a number of different ways. Short of putting the water in a vacuum and "sucking" the dissolved oxygen out, oxygen-breathing organisms such as fish take oxygen from the water through respiration, for example. It is unlikely a large body of water to become completely deoxygenated due to the presence of photosynthetic aquatic organisms (plants) and the fact that oxygen is also dissolved in the water at the water's surface.
What are the four types of water ecosystems?
The four types of Aquatic Ecosystems are - 1. Oceans are the largest of the ecosystems covering more than 70 % of the earth's surface. 2. Freshwater bodies like lakes and ponds 3. Flowing fresh water like rivers and streams 4. Wetlands with wet soil and plants that grow in this type of soil
Why is it important that fresh water flows over the Earth's surface?
It is important that fresh water flows over the Earth's surface because it supports diverse ecosystems, provides drinking water for humans and animals, and helps in essential natural processes like nutrient cycling and sediment transport. Additionally, the movement of freshwater is crucial for maintaining water quality and preventing stagnation, which can lead to the buildup of pollutants and affect the health of aquatic organisms.
