Food is digested, or broken down, so that the nutrients can be extracted for use by the body as it passes through the digestive system. If food wasn't digested you would not have energy required to run vital chemical reactions and eventually resulting death

Food has to be digested into smaller component nutrients that are then absorbed and used throughout your body. Calories in food provide your body with the energy it needs to complete vital processes such as cellular maintenance and reproduction, and respiration. also you might get fat and you die

Answer:

either RNA or DNA

Explanation:

The advancement of biomedical research techniques and molecular biology has led to the observation of the close relationship between certain viruses and some cancers in various animals. Thus, it has been shown that several DNA and RNA viruses are oncogenic in a wide variety of animals, from amphibians to primates, and there is growing evidence that some human cancers have a viral origin.

Based on this, we can conclude that oncogenic viruses can be composed of DNA or RNA.

How does non-human life in an urban ecosystem differ from non-human life in an undeveloped forest ecosystem? (Site 1)
ahrayia [7]

Answer:

- Urban ecosystem: highly disturbed systems. Air, water and soil pollution by various pollutants.  

- Undeveloped forest ecosystem: non disturbed systems. Low or null levels of pollution.

Explanation:

An urban ecosystem can be defined as the community of plants, animals, and humans inhabiting an urban environment. Urban ecosystems are composed of human-built physical structures (e.g., buildings, roads, sewers, railways) and green patches (e.g., parks, greenways, urban streams). In general, urban ecosystems are highly disturbed and contain high levels of pollution. In urban areas, plant life is generally overrepresented by non-native and invasive species. Moreover, animal life primarily consists of pets (e.g., dogs, cats, ornamental birds, ornamental fish) and natural species adapted to human activities, which mainly include small animals (e.g., insects). Moreover, a forest ecosystem is defined as a natural woodland unit composed of 1-biotic factors such as plants (e.g., trees) animals (e.g., insects, birds) and micro-organisms, and 2-abiotic factors (e.g., water, oxygen, carbon, nitrogen, sulfur, etc). Forest ecosystems contain low or null levels of pollutants in the air, soil and water. Forest environments represent self-regulating systems that have not been altered or manipulated by human exploitation. In consequence, in forest ecosystems, non-human life is appropriately represented by native flora and fauna.
