Is called autotroph organisms that create organic molecules needed for survival from inorganic sources. this is achieved through photosynthesis (which is light energy) or chemosynthesis (which is chemical energy).
And photosynthesis is when autotrophs capture and convert the light energy from the sun into usable chemical energy (which is their food).
i just answered the same question like 20 min ago XD
Answer:
disturbance has destroyed population in a community
Explanation:
The secondary succession occurs after there has been some disturbance that has manged to badly damage or destroy the populations in a community. This basically means that after some catastrophic event that happened to a certain population or populations, other species moved in to colonize the freed space. There are countless examples of secondary succession in nature, and one of the best is when there is a strong volcanic eruption. The volcano manages to destroy the population of plants and animals in its close surroundings, but after the eruption ends, the space starts to be colonized by new plants and animals step by step until they create a new well functioning community.
I hope you meant, a cross between BbPp and BbPp, else for bbpp x bbpp, all the progeny will be bbpp.
We need to work out a Punnett square to determine the genotypes resulting from the cross between BbPp and BbPp. The dyhybrid cross results in 16 different genotypes, of which a few have the same phenotypes.
It can be seen that there are 4 different kinds of phenotypes present, in the ratio 9:3:3:1.
Bleaching of the coral reefs. This is caused from greenhouse gases in the atmosphere, a main cause for these gases are our vehicles we drive.
