<p>Coevolution is the process of reciprocal evolutionary change between two or more species. It leads to divergent evolution, where species become more distinct, and convergent evolution, where species develop similar traits in response to similar environmental pressures.</p> Signup and view all the answers

<p>The Biological Species Concept states that a species is a group of interbreeding organisms that can produce fertile offspring. This concept is significant as it defines a species and enables the classification of organisms.</p> Signup and view all the answers

<p>A niche refers to the way of life or role a species plays in its environment. It determines the species' resource requirements, habitat needs, and interactions with other species.</p> Signup and view all the answers

<p>Mutualism: both species benefit; commensalism: one species benefits, the other is unaffected; parasitism: one species benefits, the other is harmed. Examples: mutualism - clownfish and sea anemone; commensalism - remora fish and shark; parasitism - tapeworm and host.</p> Signup and view all the answers

<p>A trophic level is a position in a food chain or web, determined by what an organism eats. An organism's placement is determined by its diet and energy source.</p> Signup and view all the answers

<p>Autotrophs produce their own food through photosynthesis or chemosynthesis, while heterotrophs obtain energy by consuming other organisms. Examples: autotrophs - plants, algae; heterotrophs - animals, fungi.</p> Signup and view all the answers

<p>Energy is transferred from one trophic level to the next through consumption, with some energy lost at each level. The maximum number of trophic levels is typically five, due to energy loss at each level.</p> Signup and view all the answers
