Want this question answered?
hahaha
Water sunlight and air
There is the: abiotic factors (water, sunlight, soil, and rocks) hope this helped :D
in caves and deep under the sea where light wont reach
The rate at which the ecosystem produces chemical energy from sunlight.

Sunlight/energy is made into food for the plant
Two factors that influence a region's photosynthetic productivity are the availability of sunlight and the presence of nutrients. Sunlight is crucial for photosynthesis as it provides the energy needed for the process. Nutrients, such as nitrogen and phosphorus, are essential for plant growth and photosynthetic activity. Lack of either sunlight or nutrients can limit photosynthetic productivity in a region.
Sunlight is easiest to convert into energy because we see the sun everyday, meaning we can use its rays whenever it is available. sunlight can be converted into elecrticty via solar panels.
The energy first comes from the sunlight, then the producers (green plants) absorb the energy. Sunlight

One important abiotic factor in all ecosystems is sunlight. It is essential for photosynthesis, the process by which plants and some other organisms convert sunlight into energy. Sunlight also impacts temperature, which in turn affects the overall climate of an ecosystem.
We do not know of any alien lifeforms as of yet, so if they do exist we do not know how their biology works. Most ecosystems on Earth depend on sunlight, so it is likely that any ecosystems on other planets would as well.

Because there is no light. Sunlight doesn't reach that far down.
Productivity depends on a number of factors, including (1) the total amount of sunlight the biome receives, (3) rainfall during the growing season, (2) temperature, (3) variability in climate, (4) number of species living there (more species means more productivity, all other things being equal), and may other factors. Since these factors vary across the earth, productivity varies too.
