Explanation:
The ecosystem theory of evolution is a system of concepts and approaches to the study of evolution, focusing on the features and patterns of evolution of ecosystems of various levels - biocenoses, biomes and the biosphere as a whole, and not taxa (species, families, classes, and so on). The provisions of the ecosystem theory of evolution are based on two postulates:Naturalness and discreteness of ecosystems. An ecosystem is a really existing (and not isolated for the convenience of a researcher) object, which is a system of interacting biological and non-biological (eg soil, water) objects territorially and functionally delimited from other similar objects. The boundaries between ecosystems are clear enough to speak about the independent evolution of neighboring objects.
The determining role of ecosystem interactions in determining the rate and direction of population evolution. Evolution is seen as the process of creating and filling ecological niches or licenses.
Answer:
The cancerous cells go through the cell cycle at a quicker rate in comparison to the normal cells. By doing so, they miss the checkpoints in which errors are checked. They mutate and their mutations mutate and so on that results into various distinct types of mutations, and because of this, the karyotype in cancerous cells is unusual. One may find various kinds of mutations in a cancerous cell, and this is why cancerous cells act distinctly and exhibit various issues related to it.
Members of the kingdom Animalia are required to consume other organisms, whether it be a producer (grass, leaves etc.) to other organisms to obtain energy. Plants perform photosynthesis but are not in the Kingdom Animalia. Protista is the Kingdom that would most likely have organisms that can obtain energy by photosynthesis (Alge) and can consume or decompose for energy (amoebas).
Pray this helps you :)
