How will a population change if there is abundant space and food and if the population is protected from predators or disease?
If population has abundant space and food and protected from predators/diseases, then population will multiply and increase. The J-shaped curve indicates that population is undergoing exponential growth. At first, number of individuals increases slowly.
What will happen to the population growth rate when the human population reaches carrying capacity?
Explanation: The logistic population growth occurs when the growth rate of decreases as the population reaches the carrying capacity. The carrying capacity is the maximum number of individuals in a population that the environment can support. Thank.
What will happen if the population grows larger than the carrying capacity?
When there are limited resources, logistic growth will occur. This means that the growth rate decreases once the population reaches its maximum capacity.
What happens to the growth of a population when resources are unlimited?
Exponential population growth: When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce.
How does emigration affect population size?
Emigration affects long-run population size in the sending population through the loss of the emigrant’s descendants, high rates of nonmarriage due to sex imbalance, and the disruption of marital fertility among temporary labor emigrants.
What are the three things that affect the size of a population?
Population growth rate is affected by birth rates, death rates, immigration, and emigration. If a population is given unlimited amounts of food, moisture, and oxygen, and other environmental factors, it will show exponential growth.
When a population is growing logistically At what stage is the change in population size?
This accelerating pattern of increasing population size is called exponential growth.
How does the rate of population growth change as the population approaches its carrying capacity?
As a population approaches its carrying capacity, the growth rate slows because of limiting resources. Logistic Growth is density-dependent which means that the growth rate depends on the population density. When a population exceeds the carrying capacity of the environment and deaths result from a lack of resources.
Which of these will most likely happen if a plant population grows larger than the carrying capacity of its ecosystem?

| if a population grows larger than the carrying capacity of the environment, the | death rate may rise |
| water lilies do not grow in desert sand because water availability to these plants in a desert is | a limiting factor |
Which of the following would most likely occur if a population exceeded the carrying capacity of the environment?
Which of the following would most likely occur if a population exceeded the carry capacity of the environment? The birth rate would likely increase.
What type of growth can occur only when a population has unlimited resources?
45.2A: Exponential Population Growth. When resources are unlimited, a population can experience exponential growth, where its size increases at a greater and greater rate.
