How do fish maintain depth in water

Biology
2 answers:
uysha [10]3 years ago
8 0

For a fish to be buoyant, or float, it must displace less water or the same amount of water as its own body mass. ... Many fish use swim bladders to help them with quick depth changes. These bladders fill with air to help fish rise or release air so fish can sink, often in conjunction with forward movement.

<h2>Green Algae</h2>

Explanation:

  • Green algae (sing. alga) come in a heteromorph group of species and this is only a conventional name rather than biological classification. The group unites some predominant divisions like Chlorophyta and Charophyta.
  • Some species of Chlorophyta are considered to be the first ‘true’ plants by bridging between Protozoa and Plantae. Most of this division’s representatives are aquatic, they have chloroplasts and chlorophyll a and b, which are typical for plants. They could be unicellular, often colonial and even multicellular. The variety of the group is great in terms of their habitat, morpho-structure, reproductive system, etc. Some even live in symbiosis with fungi, but they are usually classified in a different division called Lichenophyta.
  • Hence, the answer is "green algae"

A sustained multi-generational association in which one group of species presumes a substantial extent of effect over the care and reproduction of another group to secure a more predictable supply of resources from that latter group is known as domestication.
