In what ways might food webs, food chains, and predator-prey relationships be different in a pond, an estuary, and the gulf of mexico?

Pond food web has an large variety of animal and plant species, estuary food web shows transfer of nutrients and the food web of Gulf of Mexico supports fishery.

Explanation:

The food web of pond is quite vast, the producer plant level produces plant tissues to support the rest of the levels of food web. The food chain of a pond is consisted of the organism like- algae, fish, snails, frogs etc.

The estuarine food web is an example of nutrient transfer between organisms, like- the invertebrates consume plants and they are consumed by small fish. The region of coral reefs and estuaries, The Gulf of Mexico gives support to fishery.

A pond can be described as a small area with water. As the area of a pond is smaller, only a few aquatic animals  will be present here. The food chains and food webs will be very simple. Fresh water animals and plants will be able to live here.

An estuary is a coastal area with more saltish water than a lake. As it has water from many rivers, hence estuary will have diversified food webs containing animals and plants who can withstand the saltish environments.

A gulf will have water from oceans and will be a lot bigger than an estuary. The organisms here will be adapted to live in saline conditions. The food chains and food webs will be complex as there will be more number of animals and plants.

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
