The answer to this question would be: necrosis
Necrosis is the death of cell caused by various injury, one of them is oxygen starvation. Cells need a constant supply of energy to sustain its life. Without oxygen, the energy produced by cells will be decreased. When the energy is depleted, the cell will not be able to use ion pumps or any organelle that need energy. This will slowly damage the cell until it dies.
Answer:
Food webs illustrate how energy flows through ecosystems, including how efficiently organisms acquire and use it.
Autotrophs, producers in food webs, can be photosynthetic or chemosynthetic.
Photoautotrophs use light energy to synthesize their own food, while chemoautotrophs use inorganic molecules.
Chemoautotrophs are usually bacteria that live in ecosystems where sunlight is unavailable.
Heterotrophs cannot synthesize their own energy, but must obtain it from autotrophs or other heterotrophs; they act as consumers in food webs.

Answer) The first box represent the budding type of asexual reproduction . In budding due to the cell divison at the particular place in the organism , new individual will produced.
Second picture represent the budding in hydra. Budding is also a asexual reproduction.
Third type of asexual reproduction is found in plants it is vegetative reproduction.
Fourth is Binary fission . This is also a type of asexual reproduction, in which nucleus dicied into two new daughter cell via mitosis.
