Why is biodiversity important to aquatic ecosystems?

Aquatic species have evolved and adapted to watery habitats over millions of years. Aquatic habitats provide the food, water, shelter, and space essential for the survival of aquatic animals and plants. The greater the diversity of habitats, whether in water or on land, the greater will be the biodiversity.

What is biodiversity in aquatic ecosystem?

Aquatic biodiversity can be defined as the variety of life and the ecosystems that make up the freshwater, tidal, and marine regions of the world and their interactions. Aquatic biodiversity encompasses freshwater ecosystems, including lakes, ponds, reservoirs, rivers, streams, groundwater, and wetlands.

Why is biodiversity important 5 Reasons?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. … A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

Where is biodiversity greatest in aquatic ecosystems?

Aquatic biodiversity is greatest in tropical latitudes. For example, an estimated 3,000 species of fish are found in the Amazon River alone. Coral reef habitats also have extremely high biodiversity; nearly a quarter of all known marine species are found in coral reefs.

How does biodiversity affect the ocean?

The ocean is home to millions of species. The health of the oceans is strongly dependent upon this marine biodiversity. … Their feeding, development and breeding, as well as the relationships between species are affected. Rising temperatures lead to different behaviour patterns according to species.

Why are aquatic species important?

We depend on many aquatic plants and animals, and their ecological functions, for our survival. … Our aquatic wildlife are important sources of food, energy, jobs, atmospheric oxygen, buffers against new diseases, pests, and predators, and protection against food shortages and global climate change.

What is biodiversity and its importance?

Biodiversity includes the number of different organisms and their relative frequencies in an ecosystem. It also reflects the organization of organisms at different levels. Biodiversity holds ecological and economic significance. It provides us with nourishment, housing, fuel, clothing and several other resources.

Why is high biodiversity advantageous over low biodiversity?

Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.

What can decrease aquatic species?

There are many reasons for water pollution that affected negatively biodiversity. The planet’s biological diversity is affected greatly by any human activity. Six threats affect aquatic biodiversity; climate change, overexploitation, water pollution, habitat degradation, flow modification and exotic species invasion.

Why does the ocean have high biodiversity?

` The marine environment has a very high biodiversity because 32 out of the 33 described animal phyla are represented in there.

How is biodiversity affected by ocean acidification?

Damage to tropical coral reefs, which are home to one quarter of all marine species, could drastically reduce the ocean’s biodiversity. … But as acidification continues, the ocean will take up less and less carbon dioxide—meaning we may see an increase in the rate of global warming.
