The population depends on  the carrying capacity of the environment. In the environment the organisms need Food, H2O, O2, and shelter to survive.

limiting factors- A limiting factor in a system is an input or variable such that a small change in it from the present value would cause a non-negligible change in an output or other measure of the system. A factor which is not limiting over a certain domain of starting conditions may yet be limiting over another domain of starting conditions, including that of the factor in question. ' The identification of a factor as limiting is of use only in distinction to one or more other factors which is/are non-limiting. Disciplines differ in their use of the term as to whether they admit of the simultaneous existence of more than one limiting factor (which may then be called "co-limiting"), but they all require the existence of at least one non-limiting factor when the terms are used. When all factors are limiting, none are.

The predator is the tiger-shark
and the prey is the seal.
The more tiger-sharks means less seals for the tiger-shark to eat, but the more seals means there are less tiger-sharks to eat the seal.

Producer-Ecology An organism, such as a green plant, that produces its own food through photosynthesis or chemosynthesis and constitutes the firsttrophic level in a food chain; an autotroph.EX  Algae
Carnivore-an animal that feeds on flesh. EX Tiger Shark
Omnivore- Omnivores are often opportunistic, general feeders that lack carnivore or herbivore specializations for acquiring or processing food, but which nevertheless consume both animals and plants. EX Titan triggerfish
Scavenger-an animal that feeds on carrion, dead plant material, or refuse. EX  Caribbean reef squid.
Decomposer- Decomposers are organisms that break down dead or decaying organisms, and in doing so, carry out the natural process ofdecomposition. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get theirenergy, carbon and nutrients for growth and development. Decomposers can break down cells of other organisms using biochemical reactions that convert the prey tissue into metabolically useful chemical products, without need for internal digestion.[2] Decomposers use dead organisms and non-living organic compounds as their food source.

Food webs are more realistic than food chains because food webs are like an ecosystem each ecosystem has more than one food chain so there are many food webs.

If u removed  the seals there would be more tiger sharks and if there were more seals there would bell less tiger sharks

Shape explanation-Ecological pyramids are diagrams that illustrate how ecologically important factors, such as energy,biomass, and population size, vary between trophic levels in an ecosystem. Traditionally, these diagrams place the primary producers (photosynthetic organisms such as plants) at the bottom and the highest trophic levels at the top of the diagram. The size of the portion of the diagram associated with each trophic level illustrates the amount of energy, biomass, or number of individuals found in each trophic level.

Why producers are on the bottom of the pyramid- Producers are at the bottom of the pyramid because they are able to transform the sun’s energy into a large amount of plant energy through the process of photosynthesis. Producers are the base of energy for most food chains and food webs.

photosynthesis- Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy, CO2, and H2O to make sugar.

The chemical equation- 6CO2 + 6H2O ------> C6H12O6 + 6O2.

For photosynthesis u need Co2, H2O, And Sunlight, then it releases O2.

Photosynthesis takes place inside plant cells in small things calledchloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen.
