I hope this helps! I'm happy to answer any other questions you might have :)
Ducklings follow their mother due to imprinting.
An adaptation occurs when a species is set through a new constraint. This can be change in climate, defense mechanisms, food source, etc. Which will have to occur before an adaptation is made. For an example: in North America the climate slightly swifted. This meant smaller mammals such as rabbits would need to have a thicker coat of fur or shelter. Let's say all the thin furred rabbits died and all that remained were the thick furred rabbits. Over a span of time the rabbits have adapted through the climate. Meaning most of the population is thick furred through their DNA. Conclusively, it's a genetic characteristic that can happen very rapidly or slowly.
I hope this solved your question!
Answer:
Explanation:
A saprophyte derives its nutrients and energy form the organic matter of dead organism, wheras a parasite lives in or on another living organism and derives its nutrients and energy from that living organism.
Saprophytes derives their nutrition by feeding on dead and decaying organisms. Most saprophytes are fungus. The energy needed for performing their life functions are sourced from dead organisms. All saprophytes are therefore heterotrophs and consumers in the food chain.
Parasites are organisms that derives their nutrition from their host. They completely depend on their host to provide nourishment for them. Most parasites on the long run harms their host. An example is tapeworm and pig.
