- Demographic momentum is the population principle that states that; Populations cannot exceed their carrying capacity Youthful populations grow much faster than populations with many older people The resources of the earth are finite and so no population can grow forever We can increase production to account for the growing human populationarrow_forwardA colony of aliens reaches planet Earth in 3000 BC and set up a base in Antarctica. If their initial population is 100 and their specific growth rate is 0.02263/year and their yieid coefficient is 0.85, then in what year (AD) will they start to outcompete humans for resources negiecting resource and logistic growth limiting effects? Assume the human population 3000 BC is 50 million, the human yield coefficient is 0.75 and the human specific growth rate is 0.02/year. Answer:arrow_forwardRead and highlight ways limiting factors affect the population growth Examples of how limiting factors affect population growth Abiotic (nonliving) limiting factors include things like wildfire, hurricanes, pollutants, droughts, floods and seasonal climate extremes. These factors limit all populations in a given area regardless of the size of the population. For example, a wildfire that sweeps through a dense forest in the Everglades has a big impact on every population in the ecosystem, regardless of how big the population is. Limiting factors can also be biotic-having to do with living organisms. Competition and predation are examples of biotic living factors. Organisms compete for available resources like food, water, and shelter. If the resources are plentiful then the populations can increase because there is less competition. If the resources are decreased in an area, competition increases and population size decreases. For example Mountain chickadees (Parus gambeli) compete for…arrow_forward
- Which of the following statements about logistic growth is not correct? A population growing logistically has reached the carrying capacity of the environment in which it lives. A logistically growing population is represented by an S-shaped curve. When a population is growing logistically, it is limited by factors such as food supply and water. In a logistically growing population, the birth rate is much greater than the death rate.arrow_forwardThe global human population has surpassed 7 billion, far exceeding our population’s size throughout our history on Earth. Name some specific means by which we have apparently raised Earth’s carrying capacity for our species. Do you think we can continue to raise our carrying capacity? How might we do so? What limiting factors exist for the human population today? Might Earth’s future carrying capacity for us decrease? Why or why not?arrow_forwardTwo alien species compete for resources on a planet far far away. Their initial populations are 100 and 1000 and their specific growth rate is 0.02263/year and 0.02/year and their yield coefficient is 0.95 and 0.85 respectively. When the first species begins to consume more than 50% of the resources the other population will be inevitably be annihilated. How many years does it take for this to occur? Answer:arrow_forward
