The population size of organisms in an ecosystem is based on a variety of limiting factors. The graph
below shows how a rabbit population changed in size over a five-year time period.
Based on the information in the graph, what is the maximum number of rabbits that can obtain
what they need to survive in this ecosystem?
A.about 35
B.about 10
C.about 5
D.about 25
Answer:
A
Explanation:
In the graph below, the maximum number of rabbits that can live and survive in the ecosystem is the 35 that are present in Option A, as it is the highest carrying capacity of the ecosystem.
What is the influence of carrying capacity on rabbits?carrying capacity of the ecosystem depends upon many factors such as space, food availability, suitability, etc., and as per that, the carrying capacity differs. The graph here is plotted between the rabbit and the years, so the ecosystem can only support up to 35 rabbits, and any more would result in rabbit decline due to fewer foods and unsuitability of the environment.
Hence, in the graph below, the maximum number of rabbits that can live and survive in the ecosystem is the 35 that are present in Option A, as it is the highest carrying capacity of the ecosystem.

Describe the movement of Earth’s mantle. Explain how convection currents can cause tectonic plates to move.
Answer:
Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other.
Convection currents from core radioactive decay rise and fall in the mantle. Convection currents move plates. Plates separate near convection currents. Plates converge at convection currents.
What are convection currents?Convection currents are caused by differential heating. Warm, less dense, lighter material rises while cool, more dense, heavier material sinks. Convection currents are patterns of circulation that are produced by this movement in the Earth's mantle, oceans, and atmosphere.
Convection currents are produced by radioactive decay in the core and are caused by heat rising and falling inside the mantle. The plates are moved by convection currents. Plates separate where convection currents split close to the Earth's crust. Plates move in the direction of one another where convection currents converge.

There are no competing organisms in secondary succession.
The soil is already present at the start of secondary succession.
Pioneer species in secondary succession include bacteria.
Answer:
The soil is already present at the start of secondary succession.
Explanation:
Secondary succession is usually faster than primary succession because soil and nutrients are already present due to 'normalization' by previous pioneer species.

first answer (melted rock in the interior of the earth cools after so many years, turns to solid rock. after plates into each other, mountains form due to pressure which brings the rock on the earth's surface. another way is when rocks flow out with lava, the lava cools and hardens into a rock). this is my first answer. Answer about how you think melted rock deep within Earth could change over time. Would you revise your answer now? If so, how? If not, explain why.
Melted rock within the Earth changes over time crystallization and forms igneous rocks.
What is an igneous rock?One of the three primary rock types, along with sedimentary and metamorphic rocks, is an igneous rock, also known as magmatic rock. When lava or magma cools and solidifies, igneous rock is created. The partial melting of pre-existing materials in the mantle or crust of a planet can produce the magma.
Based on their chemical makeup, igneous rocks can be categorised into four groups: felsic, intermediate, mafic, and ultramafic. Most of the crust of the earth is made up of igneous rock.
The most typical igneous plutonic rock is granite. contains essential quartz, plagioclase, and alkali feldspar; hornblende, biotite, and/or muscovite are frequently present.
