Reducing the activation energy can increase the rate of a reaction. Reducing the activation energy would mean that less energy is required to process a reaction, whereas increasing activation energy would require more energy to process a reaction.
Not sure if you still need the answer but its number Three, they are the decomposers in many ecosystems
Answer:
Yes, a plant can reproduce without another plant involved.

Two ways in which carbon dioxide is released into the atmosphere are burning of fossil fuels such as petrol and coal etc and respiration process.
Explanation:
This type of reproduction occurs in non seed bearing plants such as ferns and mosses etc. These plants reproduce by the formation of spores. Spore formation is a type of asexual reproduction in which only one plant is involved. In cellular respiration, glucose molecule is broken down and energy is released with carbon dioxide gas. Fossil fuels are also responsible for the emission of carbon dioxide gas after burning in vehicles and industries.
