Answer:
Because of the angle of the Earth relative to the sun. The higher the sun is in the sky, the higher the UV radiation level.
Explanation:
So, the lattitudes toward the poles that receive sunlight are at an oblique angle, with that being said, the amount of radiation is spread to a larger area than the equator.
Thank you for the information. But what is the question?
Shale is a fine-grained, clastic sedimentary rock composed of mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. The ratio of clay to other minerals is variable.
so the statement is FALSE
A biotic factor is all of the students in the classroom.
Hope this helps!!
1. Bees pollinate flowers and flowers provide nectar for the bees. "M"
2. A tapeworm attaches to the intestines of animals and absorbs their nutrients. "P"
3.Tiny birds helping to keep a crocodile's mouth clean by eating scraps of
food caught between the crocodile's teeth. "M"
4. A tree frog using a plant for shelter from the rain. "C"
5. A tick feeding on the blood of a deer. "P"
Explanation:
Mutualism : If 2 or more species are having an association and the relation is useful to both the organisms in relation, is termed 'mutualism'.
eg: In pollination bees transfer pollens and help reproduce flowering plants and bees get nutrition from the nector.
The plover bird comes to crocodile's mouth as it gives invitation to it to cleanse its mouth and food stuck between the teeth because crocodile cannot go flossing. In turn plover birds gets its food. In this relation both bird and crocodile benefited.
Commensalism: This is a relation between two organisms or species in which one partner is benefited while other neither gets harmed nor benefited.
eg :A tree frog utilizes the shade of plants and hide in the plant to get saved from prey in turn plant does not get anything.
Parasitism: In this association parasite lives in the organism and benefits from it but host gets harmed with this association.
eg: The tapeworm living in intestine of animals attaches to draw nutrition in turn animal gets disease caused by it.
Tick receive nutrition and the deer gets the disease.
