Anaerobic respiration is a function that can provide energy to organisms in place of, or in the absence of oxygen, so choice D. would be accurate.
A uniform region occupies an area based on a homogeneous characteristic is a true statement. Regions can also be based on ecological features and as well as the location of it region itself.
A volcanic winter is a reduction in global temperatures caused by volcanic ash and droplets of sulfuric acid and water obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, particularly explosive volcanic eruption.
The exact reproduction of an individual from cellular tissue is called cloning.
Cloning is a scientific technique that is used to produce identical copies of an individual having similar genetic information.
In this process, a complete cell, tissue, gene, even an entire organism can be cloned.
A clone can be produced either by artificial or natural methods.
In nature, some unicellular organisms such as bacteria produce multiple copies of themselves by means of asexual reproduction.
The first ever human clone was named Eve in December 2002.

Answer:
Autotrophs are organisms that use light energy or energy stored in chemical compounds to make their own food.
1st order heterotrophs are organisms that eat only plants
2nd order heterotrophs are organisms that eat herbivores
3rd order heterotrophs: organisms that eat herbivores and other carnivores
Top group: carnivores
Explanation:
Producers are named as such because they produce their own food either by photosynthesis or chemosynthesis. These organisms are called autotrophs and include plants.
There are various levels of consumers. The first is first order heterotrophs, which feed on the producers. These are herbivores and include, for example, a deer feeding on grass.
The next is second order heterotrophs, which feed on the first order heterotrophs. E.g. an owl eating a mouse. These are carnivores
The next layer are also carnivores, third order heterotrophs which eat second order heterotrophs, for example a lion eating a zebra.
