What is the underwater climate of your marine ecosystem? 

The underwater climate of my marine ecosystem is a cold, dark deep sea. The climate gradually gets warmer as you get closer to the surface.

Describe the water temperature, salinity, movement, depth, and color of your aquatic ecosystem.

In my aquatic ecosystem, the water temperature tends to decrease with depth, becoming colder at deeper levels. The salinity of the water is generally consistent throughout, with the highest concentrations near the surface due to evaporation. Movement is driven by ocean currents created by differences in temperature and salinity. Depth varies greatly, with shallow coastal areas contrasting deep ocean trenches. The color is typically blue.

How much sunlight does your ecosystem receive each day?

My aquatic ecosystem receives tons of sunlight each day

Based on the amount of sunlight it receives each day, what aquatic zone do they live in?

My creature lives in the epipelagic zone.

Is your water source freshwater, saltwater, or brackish water?

My water source is saltwater.

Is your ecosystem connected to a freshwater source? 

My ecosystem is not connected to a freshwater source.

What seasonal changes occur in your ecosystem? 

Summer: Warmer water temperatures promote increased plankton growth and higher activity levels in many marine organisms.

Winter: Colder temperatures can lead to reduced plankton growth and migration of certain species towards warmer waters.

What would happen to the food web if all of the primary consumers became extinct?  Explain and give examples.

In my food web if all primary consumers became extinct there would be an overpopulation of producers. Secondary, tertiary, and quaternary consumers would slowly start to die off from the lack of food. For example, in a food chain if zooplankton became extinct, nothing would be feeding on the phytoplankton; the anchovy that feed on the zooplankton no longer have a source of food which would lead to the consumers feeding on the anchovy to no longer have a food source and so on.

What would happen if all of the decomposers were removed? Explain and give examples.  

If all of the decomposers were removed, the dead organic matter would rapidly accumulate, leading to a disruption in the nutrient cycle. For example, if bacteria became extinct, the producers would lack essential nurtrients to grow which leads to the decline of the overall ecosystem.
