Test: Abiotic & Biotic Factors - JAMB MCQ

Abiotic factors are non-living factors that affect the distribution of organisms. Temperature is one such factor that can have a significant impact on the types of organisms that can survive and thrive in a particular area.

Biotic factors are living factors that can influence the distribution of organisms. Disease-causing pathogens, such as bacteria or viruses, can limit the distribution of certain organisms by causing diseases that affect their survival.

The availability of water is an abiotic factor because it is a non-living component of the environment that can greatly impact the distribution and survival of organisms.

Sunlight is necessary for photosynthesis, the process by which plants convert light energy into chemical energy. Without sunlight, plants would not be able to carry out photosynthesis and would struggle to survive.

Biotic factors include living components of the environment that can influence the distribution of organisms. Soil fertility, which refers to the availability of essential nutrients for plant growth, can significantly affect the types of plants that can thrive in a given area.

Oxygen levels in aquatic environments, such as oceans, seas, and lakes, are an important abiotic factor that can affect the distribution of marine organisms. Different species have varying tolerance levels for oxygen concentration, and it can determine their distribution patterns.

Predators, which are organisms that consume other organisms, can have a significant impact on the distribution of herbivores. The presence of predators can limit the range of herbivores by creating areas of high predation risk.

Desert plants are adapted to survive in arid conditions, and the type of soil in a desert area can greatly impact their distribution. Certain desert plants are adapted to grow in sandy or rocky soils, while others may require specific soil compositions for optimal growth.

The pH level of freshwater bodies, such as rivers and lakes, can influence the distribution of fish species. Different fish species have specific pH requirements, and variations in pH can limit the survival and reproduction of certain species.

Biotic factors, such as the availability of suitable nesting sites, can significantly impact the distribution of bird species. Birds require appropriate nesting habitats to reproduce and raise their young, and the availability of such sites can determine their distribution patterns.
