Can you think of other factors that may affect a carrying capacity
professor190 [17]

Answer:

The factors that affects the carrying capacity are the "food availability,  water supply, environmental condition and living space"

Explanation:

The carrying capacity of an environment varies in different species and there are chances of being change over the time because of the various factors which is like food availability, water supply, environmental condition ad also the living space. The carrying capacity is mostly dependent upon the available resources and also the  services available in the ecosystem. The symbol for the carrying capacity is K. If the population size will increase the carrying capacity are not sustainable and hence it will degrade the habitat.

Must all species reproduce in order for the species to survive?
Airida [17]

ANSWER:

the correct answer is D.Yes; without reproduction, once the living organisms died, there would be no offspring to replace them.

TIP: bc if a species dies and it doesnt reproduce that species will go extinct, and remember every specie plays a role in life (but they are some animals that dont and are just a threat to the world). so reproducing is the only way to keep their generation going!

Two pebbles, Pebble A and Pebble B, are thrown horizontally with the same force. Pebble A's mass is 3 times the
Hitman42 [59]

Answer:

Pebble A has 1/3 the acceleration as pebble B.

Explanation:

F = m×a

mass of a = 3 × mass of b (m_a = 3 × m_b)

Same starting force, F

m_a = mass of a

m_b = mass of b

a_a = acceleration of a

a_b = acceleration of b

F = m_a × a_a = m_b × a_b

3 × m_b × a_a = m_b × a_b

3 × a_a = a_b

OR

a_a = a_b / 3
