Origin of cyanobacteria

Origin of chloroplasts

Origin of mitochondria

Origin of multicellular eukaryotes

Origin of fungal/plant symbioses.

Explanation:

At first, all living things on Earth were simple, single-celled organisms like archae and bacteria

Later, the first multicellular organisms evolved where photosynthesis led to a buildup of its waste oxygen, in the atmosphere, leading to the great oxygenation event.

Eukaryotes (complex cells with organelles) diversification accelerated when they started using oxygen for their metabolism.

Sexual reproduction, which involves the fusion of male and female reproductive cells to form a zygote in a process called fertilization is, in contrast to asexual reproduction, the primary method of reproduction for the vast majority of macroscopic organisms, including almost all eukaryotes which includes animals and plants etc, and after that, Earth's biodiversity greatly increased.

the endocrine system secretes hormones into blood and other body fluids. these chemicals are important for metabolism, growth, water and mineral balance, and the response to stress. hormones provide feedback to the brain to affect neural processing. reproductive hormones affect the development of the nervous system.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
