Yes it is true that is actually why trees curve towards the sunlight
It is true organisms have to compete for living space.
Yes, they do.
No, a tree is a biotic factor because it is a living organism that interacts with other living organisms in its environment. Abiotic factors are non-living components of an ecosystem, such as sunlight, water, and temperature.
All living organisms have to have a host to create other organisms. This includes micro organisms as well as bacterial organisms
They are the king of the food chain, so they don't really compete with other organisms besides each other. Lions compete with hyenas for food, as they are both apex predators inhabiting the same region.
There are two factors in an environment. Biotic factors and abiotic factors. Biotic factors are living organisms that affect other organisms. Abiotic factors are non-living factors such as temperature, sunlight, humidity, soil, etc.
Yes, they do.

Phytoplankton are photosynthetic organisms. They get their energy from sunlight.
othe organisms mustv compete with each other for food,water,and other things they need to survive
