Which plants are usually the first to grow during secondary succession?

1 answer:

8 0

Generation of carbonates from burnt plant material following fire disturbance causes an initial increase in soil pH that can affect the rate of secondary succession, as well as what types of organisms will be able to thrive. Soil composition prior to fire disturbance also influences secondary succession, both in rate and type of dominant species growth. For example, high sand concentration was found to increase the chances of primary Pteridium overImperata growth in Imperata grassland. The byproducts of combustion have been shown to affect secondary succession by soil microorganisms. For example, certain fungal species such asTrichoderma polysporum and Penicillium janthinellum have a significantly decreased success rate in spore germination within fire-affected areas, reducing their ability to recolonize.

Mnenie [13.5K]

The answer is B: Response to stimuli
what response to stimuli means is that the organism reacts to something around it
the venus flytrap wouldn't just randomly close for no reason
it had to sense the fly, and react by closing.

it's not permeability because permeability means allowing things to pass through like soaking up water
unless your teacher is referring to absorbing the nutrients of the dead fly after it's been killed
but I don't think that's what this question is about

Is a gene that can be masked by dominant gene

ruslelena [56]

Answer:

i believe the answer is recessive.

Explanation:

a recessive gene can be expressed as rr instead of RR so if one does a punnet square it would show up to be Rr Rr Rr Rr, since R represents a dominant trait and r being being recessive, then the answer would be recessive. (sorry if it doesn't really make any sense)
