Darwin explained that all life came from ________________
AnnZ [28]

Answer:

one common ancestor

Explanation:

Although Darwin’s theory is often described as the theory of evolution by natural selection, most commentators recognize that common ancestry (the idea that all organisms now alive on earth and all present day fossils trace back to one or a few “original progenitors”) is an important part of the Darwinian picture.

How are the processes of photosynthesis and respiration related to one another?
Leokris [45]

<u>Answer:</u>

Photosynthesis and respiration are so interrelated with each other that one’s product are used as another’s reactant.

<u>Explanation:</u>

  • Photosynthesis is a process used by organisms to convert 'light energy' into 'chemical energy', which is used as a source of energy for the organism.
  • Respiration is a process in which glucose and oxygen is used to create ATP for the survival of the organism.
  • During photosynthesis 'water and carbon dioxide' reacts in presence of light to create oxygen and glucose.
  • Without photosynthesis and respiration life ceases to exist on earth.

How does genetic diversity affect biodiversity in an area provide an example
ra1l [238]

When humans farm large plantation of one cash crop, they reduce the biodiversity of the region because they reduce the genetic diversity of the species in the environment. A reduction in genetic diversity means that the genetic variability of the species is reduced  hence there are fewer sub-species in the environment. This ultimately reduces the biodiversity of the ecosystem -  which is the variability among all the living organisms in the environment.

Disturbances to an ecosystem, such as fires and floods, are often seen as negative. Describe a situation where
trasher [3.6K]

Answer:

A biological community in which association takes place between the organisms and their physical surroundings is termed as an ecosystem. It can also be defined as an association between the nonliving and living components found within the environment. A particular geographical region, which is specified for the species thriving within it is known as a biome.  

A branch of science, which deals with the natural procedures that comprise fire within an ecosystem and the ecological influences it imparts, the association between the biotic and the abiotic constituents of an ecosystem with the fire, and the role played by fire within an ecosystem is termed as a fire ecology.  

Different kinds of ecosystems like savanna, prairie, coniferous forests and chaparral have originated by the contribution of the fire, which plays an essential role in the renewal and vitality of the habitat. Different kind of plant species needs the assistance of fire to establish, to reproduce, or to germinate. In case, if the suppression of wildfire takes place, it will eventually result in the eradication of various plant species and the animals that rely upon them.
