Below is a carrying capacity graph of a meerkat population in an African savanna. Meerkats are omnivores and eat a variety of organisms, such as fruit, insects, scorpions and lizards. Predators of the meerkat include hyenas and eagles. What is a possible cause for the sudden change in population of meerkats after year 3?
A. Warmer weather increased the number of insects.
B. The number of eagles was reduced due to disease.
C. A fire reduced the amount of grass and fruit available.
D.A lack of predators increased the lizard population.
Answers
A fire reduced the amount of grass and fruit available.
What is carrying capacity in ecology?
In ecology, carrying capacity is measured as the maximum load of an environment. The physical features present in the environment act as limiting factors (e.g. food, water, competition, etc.). Thus, the population limit can be expected to depend on these factors.
What is carrying capacity of an ecosystem?
Populations grow at a rate limited by the availability of the Earth’s resources. A population may grow at a faster rate and follow a J-shaped curve. When the birth rate surpasses the death rate of the species, this results in exponential growth.

Describe the steps of the rock cycle and relate them to weathering, erosion, plate tectonics, and mountain building
Answers
Answer:
The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions. For example, an igneous rock such as basalt may break down and dissolve when exposed to the atmosphere, or melt as it is subducted under a continent. Due to the driving forces of the rock cycle, plate tectonics and the water cycle, rocks do not remain in equilibrium and change as they encounter new environments. The rock cycle explains how the three rock types are related to each other, and how processes change from one type to another over time. This cyclical aspect makes rock change a geologic cycle and, on planets containing life, a biogeochemical cycle.
Explanation:
The Rock cycle is the geological concept, in which transitions between sedimentary, metamorphic, and igneous rocks over geologic time occurs. The transitions between rocks occur due to weathering, metamorphism, erosion, and sedimentation.
The steps involved in the rock cycle are:
Weathering refers to the breakdown or dissolving of the rocks on the Earth's surface. After the weathering, the process of erosion occurs in which rock particles and minerals are transported via plants, animals, wind, and water. The igneous rocks are formed by plate tectonics. The heat from the mantle fuels the plate tectonics, which converts the igneous and sedimentary rocks into metamorphic rocks. Mountain building is caused by the intense deformation of layered rocks and the activity of metamorphic and igneous rocks in the orogenic stage.
Thus, the rock cycle is involved in various processes and transitions among different types of rocks that occur in the rock cycle.

Answer:
They live in a forest that has trees with dark colored bark.

Because the dark colored moths can blend in better with dark bark than light colored moths do, they don't stand out as much, so the predators(the birds) will eat the ones that they can find easier, which happens to be the light colored moths.

The carbon dioxide from fossil fuels acts is the same as the carbon dioxide that we breath out... Why does burning fossil fuels cause global warming if breathing doesn't?
The carbon in fossil fuels is very very old. The carbon that we breath out is much newer.
The carbon in fossil fuels was unable to reach the atmosphere until humans dug it up. The carbon we breath out was already moving around on the surface.
Plants don't like to absorb the carbon that comes from fossil fuels. However, plants love to use the carbon that we breath out.
For some reason the carbon from fossil fuels is stronger than the carbon that we breath out.
Answers
Answer:
When we breathe out CO2 There are a lot of plants to take carbon dioxide away, but due to the cutting down of forests there are fewer trees to absorb CO2 and more burning of fossil fuels is causing CO2 levels in the atmosphere to increase

Explain the relationship between the variation in estradiol and progesterone rates in the female body and the events that occur in the uterus during the menstrual cycle
Answers
Answer:
The ruptured follicle closes after releasing the egg and forms a corpus luteum, which produces progesterone. During most of this phase, the estrogen level is high. Progesterone and estrogen cause the lining of the uterus to thicken more, to prepare for possible fertilization.
Progesterone and estrogen are necessary to prepare the uterus for menstruation, and their release is triggered by the hypothalamus. Once you reach puberty, the ovaries release a single egg each month (the ovaries typically alternate releasing an egg)—this is called ovulation.
