Asap i need dba list the interactions. list the harmful interactions. explain symbiosis in your own words. what are the two types of biological interactions? what is parasitism? give two examples in which the host is harmed. what is a predator? give two examples . what is prey? what animals would be considered prey of the two predators that you mentioned? what is mutualism? give two examples. what is commensalism? give two examples. how does predation affect an ecosystem? how does competition affect an ecosystem? explain in your own words how competition works in an ecosystem. how did the backyard bird feeders in the article increase competition in that ecosystem?

1. Symbiosis is the interaction between two different living organisms living together to survive.

2. Parasitism is the relationship between two species of plants or animals in which one benefits at the expense of the other, sometimes without killing the host organism.

Example: Tapeworms attach themselves to the insides of the intestines of animals.They get food by eating the host's partly digested food, depriving the host of nutrients. Another example is fleas. they harm their hosts, by biting their skin, sucking their blood, and causing them to itch.

3. A predator is an animal that preys on other animals, usually for food.

Example: A lion or a bear.

4. The definition of prey is where one organism, the predator, kills and eats another organism.

Example: The prey to a lion would be a zebra, and the prey to a bear would be a fish.

5. Mutualism is where two different species live together to survive at each others advantage.

Example: Oxpeckers and rhinos.

6. Commensalism is where one organism benefits and the other is not harmed or benefited.

Example: Barnacles and Whales.

7. Predation helps keep herbivores from growing into too large of crowds, and predation keep the population of animals in general in check.

8. Competition both within and between species is an important topic in ecology, especially community ecology.

9. This is in your own words :)

10. I don't know what article you read

I hope this all helps :D

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)

the answer is "a.) well–developed vascular system."
