3A- Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.

3B- Negative feedback loops are used to maintain homeostasis and achieve the set point within a system. Negative feedback loops are characterized by their ability to either increase or decrease a stimulus, inhibiting the ability of the stimulus to continue as it did prior to sensing of the receptor.

Hope I’ve helped ;)

A producer cannot make sugars in the absence of light, the correct option is A.

<h3>What are producers?</h3>

Producers, also known as autotrophs, are lifeforms that produce their own food.

They obtain energy from chemicals or the sun and transform it into usable energy in the form of sugar or food using water.

Plants and algae can produce their own food by harnessing solar energy. These organisms are referred to as producers because they generate their own food.

Thus, the correct option is A.

This taxonomic category is at level below Kingdom and above Class (e.g Arthropoda, Chordata, Mollusca)

2. plant that lives on decaying organic matter-saprophyte  

Saprotrophic plants or saprophytes use saprotrophic nutrition meaning that have extracellular digestion to process death organic matter.

3. break down of complex molecules into simpler ones- fermentation  

Fermentation is a metabolic process that breaks down organic substrates in order to obtain energy. These processes are performed without the presence of oxygen (anaerobic processes).

4. multi-nucleated thread-like structures of fungi hyphae

This is one of the basic structural unit of fungi-long, filamentous structure that can form network-micelium. It is used for vegetative reproduction.

5. mycelia responsible for obtaining food from non-living organic material rhizoids

Rhizodis are unicellular or multicellular stuctures (branching hyphae) found in fungi that are similar to root hairs of plants. These structures are involved in saprotrophic nutrition of fungi.

6. asexual reproduction of yeast budding  

Budding is a type of asexual reproduction in which a new organism develops from some generative anatomical part of the parent organism.

7. a group of hyphae mycelia

Mycelum is fungi’s vegetative body that consists of network of branching hyphae.

8. reproductive cells which can tolerate bad conditions spores

Spores are reproductive structure, part of the fungi life cycle, that can be involved in sexual or asexual reproduction, vary in structure that are formed in. Spores are usually haploid and unicellular.

9. structures which house the reproductive formation fruiting

Fruit is a structure in flowering plants that contains seed and it is responsible for seed dispersal and nutrition.

10. mutually positive relationship between two species symbiosis  

Symbiosis is biological interaction between two species that can be mutualistic, commensalistic, or parasitic. More specifically, symbiosis refers to positive interaction for both members of it.

11. plant or animal which supports a parasite host

Parasitic relationship between species is the one in which organism (the parasite), lives on or in another organism (host).This relationship is positive for parasite but negative for the host.
