Answer 1

Answer:

Answer of 11 question- Coprophilous fungi (dung-loving fungi)[1] are a type of saprobic fungi that grow on animal dung. The hardy spores of coprophilous species are unwittingly consumed by herbivores from vegetation, and are excreted along with the plant matter. The fungi then flourish in the feces, before releasing their spores to the surrounding area.

Answer of 12 question- Euglenas create their own food through photosynthesis, the process of absorbing sunlight to synthesize foods from carbon dioxide and water. An eyespot at the front end of the euglena detects light, and its chloroplasts (structures that contain chlorophyll) trap the sunlight, allowing photosynthesis to occur.

Answer of 13 question- There are three major known groups of Archaebacteria: methanogens, halophiles, and thermophiles. The methanogens are anaerobic bacteria that produce methane. They are found in sewage treatment plants, bogs, and the intestinal tracts of ruminants.

Answer of 14 question- Red tide is a phenomenon caused by algal blooms (Wikipedia definition) during which algae become so numerous that they discolor coastal waters (hence the name "red tide"). The algal bloom may also deplete oxygen in the waters and/or release toxins that may cause illness in humans and other animals.

Answer 2

Answer:

11. Coprophilous fungi are those that grow and live on animal dung. Pilobolus species feed prophetically on the feces of grazing animals.

12. Euglenas create their own food through photosynthesis, the process of absorbing sunlight to synthesize food from carbon dioxide and water.

13. Major groups of archaebacteria are :

• Crenarchaeota
• Euryarchaeota
• Korarchaeota
• Thaumarchaeota
• Nanoarchaeota

14. Red tides (algal bloom) are caused by dinoflagellates. They mainly live in marine water. These organisms are red in color, so the sea appears in red color.

The toxins released by such a large number of the dinoflagellates are harmful to other aquatic organisms and it may also kill them.
