question 2
how does competition affect weaker organisms of a species?
check my answer
question 3
what abiotic factors determine the type of terrestrial biome?

Explanation:

For the first question, a habitat is the physical place where an organism lives, while a niche encompasses the organism's role, its interactions, and the resources it uses in that environment. For the second question, competition often makes it harder for weaker organisms of a species to access resources like food, water, and space, potentially leading to reduced survival and reproduction rates. For the third question, abiotic factors such as temperature, precipitation, soil type, and sunlight availability determine the type of terrestrial biome as they influence which plants and animals can survive in a particular area.

Answer:

Question 1: A habitat is the physical location of an organism, while a niche is the organism's role and resource - use in that environment.
Question 2: Competition makes it more difficult for weaker organisms of a species to access resources, reducing survival and reproduction rates.
Question 3: Temperature, precipitation, soil type, and sunlight availability are abiotic factors that determine the type of terrestrial biome.
