Which is the correct food chain?
The process of transfer of energy from producers through a series of organisms, i.e., from primary consumers to secondary consumers and from secondary consumers to tertiary consumers by process of eating and being eaten constitute a food chain.
The correct food chain is phytoplankton >> zooplankton >> fish..
What are the three types of aquatic habitat?
There are three main types of aquatic habitats: freshwater, marine, and brackish.
What are the two types of aquatic habitat?
Aquatic ecosystems are divided into two main groups based on their salinity—freshwater habitats and marine habitats. Freshwater habitats are aquatic habitats with low levels of salt, less than one percent. They include rivers, lakes, streams, ponds, swamps, wetlands, bogs and lagoons.
What eats plankton food chain?
Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Primary consumers are in turn eaten by fish, small sharks, corals, and baleen whales.
What effects might food production have on the environment?
Food production contributes, for example, to climate change, eutrophication and acid rain, as well as the depletion of biodiversity. It is also a considerable drain on other resources, such as nutrients, land area, energy, and water.
What is an aquaculture facility?
Aquaculture facility means any facility used for propagating, rearing, or producing aquatic wildlife or aquaculture products. … Aquaculture facility means a defined managed water area or facility for the maintenance or production of harvestable freshwater, estuarine or marine plants and/or animals.
What is food chain explain with diagram?
A food chain is a linear diagram showing how energy moves through an ecosystem. It shows only one pathway out of the many possibilities in a specific ecosystem.
What is aquatic food production?
[Aquaculture is the farming of aquatic organisms in both coastal and inland areas that involves intervention in the rearing process to enhance production.] … Distinguish between capture fisheries and aquaculture.
Who eats crab?
Seals and sea otters are two predatory sea mammals that love crabs. In the Antarctic Ocean, the Weddell seal and the aptly-named crabeater seal both enjoy feasting on crustaceans. Shore birds such as seagulls go after crabs that are stuck on the shore or in tide pools during low tide.
What is food chain and example?
A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected. eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal.
Is shrimp a decomposer?
In a food web nutrients are recycled in the end by decomposers. Animals like shrimp and crabs can break the materials down to detritus. Then bacteria reduce the detritus to nutrients. Decomposers work at every level, setting free nutrients that form an essential part of the total food web.
What is aquatic body?
An aquatic ecosystem is an ecosystem in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems.
Why the harvesting of a named aquatic species may be controversial?
Harvesting some species, such as seals and whales, can be controversial. … Issues around aquaculture include: loss of habitats, pollution (with feed, antifouling agents, antibiotics and other medicines added to fish pens), spread of diseases and escaped species (some involving genetically modified organisms).
How can food sustainability be improved?
Sustainable agriculture practicesRotating crops and embracing diversity. … Planting cover crops. … Reducing or eliminating tillage. … Applying integrated pest management (IPM). … Integrating livestock and crops. … Adopting agroforestry practices. … Managing whole systems and landscapes.
Why are the highest rates of productivity are found near coastlines or in shallow seas?
Coastal waters and shallow seas tend to be productive, because: … Sunlight may penetrate down to the sea floor resulting in relatively high levels of light that drives photosynthesis. Fresh water ecosystems. Freshwater ecosystems include lakes, rivers, streams and wetlands.
What are examples of a food chain?
Food Chains on LandNectar (flowers) – butterflies – small birds – foxes.Dandelions – snail – frog – bird – fox.Dead plants – centipede – robin – raccoon.Decayed plants – worms – birds – eagles.Fruits – tapir – jaguar.Fruits – monkeys – monkey-eating eagle.Grass – antelope – tiger – vulture.Grass – cow – man – maggot.More items…
What are the 4 types of aquatic ecosystems?
Description of the Four Types of Aquatic EcosystemsThe Largest Ecosystem. Oceans are the largest of the ecosystems, covering more than 70 percent of the Earth’s surface. … Rainforests of the Sea. … Looking at Shorelines. … Lakes and Ponds. … Flowing Freshwater. … Wet Soils and Water-Loving Plants.
What is aquatic food chain?
A food chain is a simple linkage of producers to consumers through feeding relationships. … For example, when a small fish eats an aquatic insect, and a larger fish eats the small fish, the two fish and the insect are linked in a food chain.
