Answer:
A & C
Explanation:
Primary producers are always at the bottom of the food chain because they are the entry point of energy into the ecosystem. The producers are organisms that produce their own 'food' from abiotic factors and include photoautotrophs and chemoautotrophs. These organisms are then consumed by primary consumers who are subsequently consumed by secondary consumers who are subsequently consumed by tertiary consumers to decomposers. The number of consumers up the food chains can vary with ecososyems and can be an indication of how biodiverse they are. This is how energy and matter are passed up an ecosystem and recycled.

Ans.
Fungi are eukaryotic (both unicellular and multicellular), heterotropic organisms that depend on plants, animals, or organic dead matter for food. Fungi reproduce either sexually or asexually.
-Mating types show molecular mechanisms to regulate compatibility in sexual reproduction in fungi. The organisms of class basidiomycota, such as club fungi, have bipolar mating system, means they have both positive and negative mating strand. The option 1). correctly matches with D). club fungi.
-The fruiting bodies of fungi are defined as the specialized structures that produce spores. In sac fungi, fruiting bodies are formed sexual reproduction that fills thousands of asci or spores in it. The option 2). correctly matches with C). sac fungi.
-The chytrids show one of the early lineages of fungi. They possess a cell wall of chitin, a flagellum, absorptive structures for nutrition. The option 3). correctly matches with A). chytrids.
- The common molds include various microscopic fungal species, which grow in the form of hyphae (multicellular filamentous structures). They are found nearly everywhere and show all forms of nutrition. They feed from dead organic matter, plants, and animals (as using them hosts). The option 4). correctly matches with B). common molds.
