The following are the expected ranks of biomes based on increased oxygen for plant growth and they are
1. Desert,
2. Grassland
3. Temperate Forest
4. Tropical Rain Forest
The desert biome is formed owing to very limited annual rainfall and it covers approximately 20% of the Earth. The Grassland is predominantly dominated by grasses while the temperature in the temperate forest is around 10 degree celcius. The plants and trees in this biomes develop special adaptations for their survival. However, the rain forest is characterized with all year round rain hence the biome is moist. The biome is known for vegetations with dense canopies.
Frost wedging is a type of physical weathering of rock.
Explanation:
Physical or mechanical weathering affects the rock structurally but does not change the chemical composition. Mechanical forces will rub, break or shatter the rock surfaces. Wedging, abrasion, exfoliation are different types of physical weathering.
Water is one of the main sources which alter the structure of the rocks physically.
Frost wedging occurring due to flow of freezing water over the rocks. This frozen water enters the rock through the cracks and crevices on the rock surface, and will expand inside and makes the rocks to crack further and breaks it apart.
Answer:
- sporangia , zygospore
- Basidiomycota
- hyphae, mycellium
- lichen
- mycorrhiza
- Ascomycota
Explanation:
1. Zygomycetes reproduce asexually through the haploid spores formed in sporangia, or sexually through diploid nuclei formed in zygospore.
2. Basidiomycota are called club fungi because they produce club-shaped reproductive structures like toadstools.
3. The vegetative body of most fungi is called a hyphae, which consists of an interwoven mass of threadlike filaments called mycelium.
4. A lichen is a symbiotic association between a fungus and a single-celled alga or cyanobacteria. The fungus protects the photosynthesizer from harsh conditions while consuming the extra nutrients it produces.
5. A mycorrhiza is a symbiotic association between a fungus and the roots of a plant. The fungus receives energy-rich sugar molecules produced by the plant while passing minerals and nutrients from the soil to the root.
6. Ascomycota, also known as sac fungi, include morels, yeasts, and the species that produces penicillin.
Answer:
Changes of state are physical changes. They occur when matter absorbs or loses energy. Processes in which matter changes between liquid and solid states are freezing and melting. Processes in which matter changes between liquid and gaseous states are vaporization, evaporation, and condensation.
Abiotic factors are factors that include non-living parts of the environment which could be significant or essential to living organisms. Water is a non-living environment and it helps in giving life to plants and other organisms. Thus deemed abiotic.
