State true or false.
The number of species that may live in an ecosystem is determined by the resources available as well as abiotic variables such as light and water availability, temperature range, and soil type.

Every aspect of an ecosystem, whether directly or indirectly, is reliant on the other.
Is the above statement true or false?

• It's true that each and every aspect of one ecosystem, whether directly or indirectly reliant on the other ecosystem.

Rocks, temperature, and humidity are examples of ________________.

• Rocks, temperature and humidity the all are non living and so can be said as abiotic.

Plants, animals, and other species are examples of ___________.

• Animals, plants and other species are biotic as they all have characteristics of living.

Which of the following is the best example of exponential growth?

• Bacteria reproduce very rapidly which leads an exponential growth in their population.

y(t) = ae^kt is the formula to calculate ______growth.

• y(t) = ae^kt is the formula of exponential growth.

What is exponential growth?

• y(t)= ae^kt is the formula of exponential growth.

When resources become depleted, what happens to the population?

• Depletion of resources leads to decrease in resources and due to which compitition in the animals increases which leads decrease in population.

English clergyman Thomas Malthus published a book in which year?

• He was an English economist and told about relationship between natural resources and growth of populations.

When resources are unlimited, what does the population experience?

• Unlimited natural resources decrease compitition between animals for the resources which leads rapid increase in the population.

Which of the following is a predator?

• Lion is an example of predators.

Which of the following is prey?

• Predators feed on other creatures and the creatures are known as preys.

State true or false.
One species is feeding on the other species in a predator-prey relationship.

• All the organisms on earth compete with each other for limited resources.
• One species feed on other species in predator - prey relationship.

Which theory was proposed by Charles Darwin?

• According to the theory of Charles Darwin, nature allows only those organisms to survive which compete for the resources and survive.
• Only these organisms can pass their characteristics to next generation.

State true or false.
When infinite natural resources are available, only then exponential growth is possible, which is not the case in the real world.

• Exponential growth is a sharp increase over time in a population which is caused by unlimited natural resources.

Logistic growth shows which type of curve?

Logistic growth shows growth of a population in three parts:

• Firstly increase in population slowly
• Then it increases rapidly
• And when there is enough increase in the population, it starts getting decrease.
