no food for organisms no oxygen in the atmosphere no trees or flowering plants no products based on trees or plants (building materials, medicines, fuels, fibers) no fossil fuels

Explanation:

Plants are the organisms which has the ability to make their own food in the process of photosynthesis. The food which is produced by plants is also used by primary consumer and omnivores like humans. It also provide oxygen to all living organisms. When compressed in the soil at high temperature and pressure for centuries, these plants are converted into fossil fuels such as coal. Its wood is also used in furniture and building materials.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex
