Fires disrupt the equilibrium of an ecosystem. The results of a fire include a resetting of plant succession. Many ecosystems have adapted to a certain frequency and intensity of wildfires, and many plant species actually require fires as part of their life cycles. Fires can open up forests and grasslands that would be too congested and shaded to allow young grasses or trees to take root. Fires in fact act as a stimulus for some seeds to germinate. These would typically be pioneer plants that are able to grow in fairly harsh and varied conditions. Fires also remove accumulated dead tree matter that can accumulate in a forest, and if wildfires are too infrequent, fires and be very intense when they do happen as they are fed by the accumulated material.
Answer:
Clearing heavily forested land ranges between $3,000 and $5,600 per acre while lightly wooded lots will only cost $500 to $2,000 per acre. The total amount you pay depends on the topography of the ground, ease of access to the site and the amount of debris you need to remove.
I have no clue if this will help but yeah
Explanation:
The sequence of species in which they disappear, in order from least to most severe would be: B. Threatened-Endangered-Extinct.
Hope this helps!
Answer:
If a species has the ability to produce that many eggs, that means it has the ability to overproduce. This is beneficial because while the parents cannot provide excessive amounts of parenting/care for each of the offspring, only the fittest will end up surviving. Once the fittest survive and reproduce, they will pass on the trait or traits that made them fitter to their offspring. Then the process will repeat, resulting in a better population over time. Thus, the amount of favorable traits will accumulate in the species; this, in other words, is a benefit to the species.
Considering the definition of density, you obtain that:
- Part A: the density of gold is 19.3 g/cm³.
- Part B: the density of iron is 7.8 g/cm³.
<h3>Definition of density</h3>
Density is defined as the property that allows to measure the amount of mass in a certain volume of a substance.
The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
density= mass÷ volume
It can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.
<h3>Density in this case</h3>
In this case, you know that:
- A sample of gold has mass of 38.6 grams and a volume of 2 cm³.
- A sample of iron has a mass of 46.8 grams and a volume of 6 cm³.
Replacing in the definition of density:
- Gold: density= 38.6 g÷ 2 cm³
- Iron: density= 46.8 g÷ 6 cm³
Solving:
- <u><em>Gold: density= 19.3 g/cm³</em></u>
- <u><em>Iron: density= 7.8 g/cm³</em></u>
In summary, the density of gold is 19.3 g/cm³ and the density of iron is 7.8 g/cm³.
