Which factor is not an important advantage of aquatic organisms living near the surface of a lake or pond?
One factor that is not an important advantage for aquatic organisms living near the surface of a lake or pond is the availability of nutrients. While surface waters may have access to sunlight for photosynthesis, deeper layers often contain a higher concentration of nutrients due to sedimentation and decomposition. Therefore, organisms relying solely on surface habitats may face limitations in nutrient availability compared to those living in deeper waters.

Name the organisms that absorb oxygen by diffusion?
Small aquatic organisms like single-celled bacteria, protozoa, and some aquatic invertebrates absorb oxygen by diffusion through their body surface, since they have a high surface area to volume ratio which allows for efficient exchange of gases.
How does respiration occur in aquatic organisms?
Aquatic organisms respirate by extracting oxygen dissolved in water through their gills or body surface. The oxygen is then delivered to their cells, where it participates in cellular respiration to produce energy. Carbon dioxide, a byproduct of respiration, is released into the surrounding water.
Why do photosynthetic organisms live on or near the surface of aquatic ecosystems?
Photosynthetic organisms need sunlight for photosynthesis, which is their primary source of energy. By living on or near the surface of aquatic ecosystems, they can capture and utilize the sunlight effectively. This placement allows them to maximize their photosynthetic activity and productivity.
What are the advantages of water as respiratory media to aquatic animals?
If an animal lives in the water, it is an advantage to be able to get oxygen from the water. If the animal must breathe air, then it has to surface frequently. If it is unable to surface for some reason, it will drown.
What are three typical pond organisms?
As the water mixes, minerals, plant matter, and othernutriens rise from the lake bottom to the surface. Calledlake turnover,this seasonal change refreshs the supply ofnutriens throughtout the lake.
How does surface tension helps organisms?
Surface tension allows organisms to walk on water, like certain insects do, by supporting their weight. It also helps organisms trap and feed on prey by creating sticky surfaces, like on the tentacles of some aquatic animals. Additionally, surface tension can assist in regulating water loss in organisms that live in arid environments.
Why is the density of water so important to life on earth?
The density of water is important for life on Earth because it allows aquatic organisms to float and control their position in the water column. This property also helps to regulate the temperature of the oceans and acts as a solvent for key biochemical reactions in living organisms. Additionally, the fact that ice is less dense than water allows for the formation of a layer on the surface of bodies of water, insulating the underlying water and protecting aquatic life during cold temperatures.
Have dead cells why is it an advantage to on the surface of the body?

What is the definition of the surface zone?
The surface zone is the top layer of a body of water where there is the most interaction with the atmosphere. It is where light penetrates and where temperature changes are most noticeable. This zone is important for supporting aquatic life and plays a crucial role in the overall health of aquatic ecosystems.
Why is the lithosphere important?
The lithosphere provides the solid surface necessary for terrestrial organisms top survive.

What are the effects of water surface tension on environment?
Water surface tension helps support small organisms and debris on the surface of bodies of water, making it easier for some organisms to move across the surface. However, it can also trap pollutants like oil and chemicals, preventing them from mixing with the water below and making cleanup efforts more challenging. Additionally, surface tension can affect nutrient uptake and gas exchange in aquatic ecosystems.
