Which level of an energy pyramid has the most energy available?

Chemistry
1 answer:
nirvana33 [79]3 years ago
8 0

7. A

The energy pyramid is simply going from the bottom having the most energy, and the top having the least. The most energy in the energy pyramid is provided by the producers. The producers are at the bottom of the energy pyramid. They are the basis of all ecosystems. The producers have the most energy because they are the ones that manage to produce food for themselves, thus they provide 100% energy, while all other levels have 10% of the previous level of the energy pyramid.

8. coyote

The trophic levels are simply divided into autotrophs, which are the ones that produce the food for themselves, primary consumers, which are feeding on the producers, and secondary consumers, which are feeding on the primary consumers. In the category of secondary consumers we have the predators. The predators are the ones that eat the primary consumers, and the coyote is falling into this category. The coyote is a predator, from the canidae family, being a carnivore that preys upon herbivores.

9. True

The invasive species are the species that have managed to reach and inhabit places that are not their native territory. This can happen in a natural way, or because of the humans. The invasive species are usually much more competitive than the native species. They manage to take their food sources, prey upon them with ease, reproduce much quicker, as well as introducing new diseases. All of that results in in easy expansion of the invasive species, while the native species decrease or even go extinct.

10. It would decrease because the greenfly population would decrease

The ladybird, or ladybug, is falling into the category of secondary consumers, thus they are predators. They feed upon small insects, mostly that are considered as pests, such as the greenfly. The greenfly is feeding on the berries. If the berry population starts to decrease, then the greenfly population will decrease as well, as the food source will be smaller. The ladybird population will too start to decrease, as the greenfly population, its prey, will be decreasing because of the decrease in the berry population.

What statement is true about the eight elements on the periodic table termed metalloids?
valina [46]

Answer:

They have properties of both metals and nonmetals

Explanation:

  • Elements in the periodic table may be divided into Metals, non-metals, and metalloids.
  • Metals are the elements that react by losing electrons to form stable positively charged ions known as cations. Examples are group 1, 2, and 3 elements together with transition elements.
  • Non-metals are those elements that react by gaining electrons to form stable negatively charged ions called anions. Examples include oxygen, carbon, sulfur, etc.
  • Metalloids, on the other hand, are elements that have both metallic and non-metallic properties.
  • Metalloids occur between metals and non-metals in the periodic table. Examples include Boron and silicon among others.

Just look at the number in front also called coefficient (you have to balance the equations first, but all the questions here are balanced, so no worries). for q1.
in the balanced equation, the number in front of aluminum oxide is 2 (2 - this number Al2O3) and for aluminium is 4 as in (4 Al). so the ratio is 2:4. simplified it is 1:2. or write it out fully
2 Al2O3: 4 Al
ignore everything after the number.
2:4
same as 1:2
Aluminium oxide to oxygen
2 Al2O3: 3 O2
2:3
aluminum to oxygen
4 Al: 3 O2
4:3

question 2
Mercury oxide to Mercury
2 HgO : 2 Hg
2:2
same as 1:1
Mercury oxide to oxygen
2 HgO : O2
since oxygen in this case does not have a number written in front of it, the default is 1.
2: 1.
you should be able to do the rest
