Why does decomposition by microbes deplete O2 ?

Number 7 and 8 only

I'm having trouble incoorporating the decomposer into my complex food web. I know that they eat dead organic matter, but I have seen many food webs on Google showing that they only eat one thing. Shouldn't there be arrows from every other organism pointing to the decomposer? Can you show me an example. Please answer soon...this project is due tomorrow.

Please explain answers well as this is practice e

Imagine a company producing Non-Biodegradable plastic which is polluting the local environment. 1. What arguments can you provide to this company to incur additional costs to reduce the environmental impact of the production and disposal of the plastic, even though production and disposal are performed by others?

Plant Physiology: 1. Plant Hormone signal transduction is an exciting field and the mode of signaling for various hormones in the cellular context have been elucidated. Compare and contrast the plant hormone Auxin and ethylene signal transductions mechanisms. (Hint. Begin at the Receptor level) 2. To cope with drought conditions, plants employ a very common mechanism of synthesizing solutes for osmotic adjustment. Describe how solutes help plant cells to cope with drought conditions. 3. Carotenoids comprise a family of orange and yellow pigments present in most photosynthetic organisms. Describe the different types of carotenoids found in photosynthetic organisms pointing to their chemical characteristics and functions. 4. ATP synthesis in chloroplast is based on the stepwise conservation of energy. Trace the conservation of energy from the initial absorption of light by the chlorophyll molecule to the final formation of a molecule of ATP. 5. Trace the path of carbon in a typical C4…

Make a simple diagram or drawing (arrows only if you want to) the interconnection of carbon and nitrogen cycle. Also, write the microorganisms (Scientific names) involved in each process. Thank you!
