Answer:
Descenso común describe cómo en biología evolutiva un grupo de organismos comparte un ancestro común más reciente. Hay evidencia de descendencia común de que toda la vida en la Tierra desciende del último ancestro común universal.
Explanation:
Answer:
Q.1: I can't help you with this, sorry :(
Q.2: Seaweed is the producer because it takes energy from the water and sun in thermal reactions.
Q.3: Phytoplankton is the second-order consumer because they eat first-order consumers.
Q.4: Whelks and crabs because they eat limpets, which eat producers, and they also eat seaweed.
Q.5: Gulls are carnivores because they eat the crabs, and so are crabs because they eat mullets
Q.6: Limpets and lobster would become less populated, but not yet endangered. Gulls would starve and probably disappear from this ecosystem.
Q.7: Whelks' numbers would decrease because of the number of lobsters consuming them, but then lobsters would starve because of the decline in their food. Then this would repeat, shaking the whole ecosystem.
A molecule is a group of two or more atoms held together by chemical bonds. A compound is a substance which is formed by two or more different types of elements which are united chemically in a fixed proportion. All molecules are not compounds. All compounds are molecules.
Matter that is not used by consumers in the food chain become "detritus". Detritus, meaning debris or waste, are materials that are missed or uneaten by consumers. Because they do not participate in higher trophic levels, these materials are left to decompose. Detritus is often considered the "missing mass" when measuring the total mass in the food chain.
