Biodiversity

• Genetic Biodiversity refers to the different characteristics of a species.
• Species Biodiversity is the variability of species that can be found in a particular environment.
• Ecosystem Biodiversity is the difference in the different environments on the Earth.
• If an organism has not adapted to its ecological niche, extinction will occur.
• Adaptation can enhance competence in finding and utilizing essential resources such as light, air, and food.
• How do whales prolong apnea?

  • High hemoglobin density in the blood and myoglobin in the muscles store a great amount of oxygen. Therefore, their capacity to hold their breath will be longer.
• Complementarity Effect

  • Darwin proposed that species diversity might increase the productivity of ecosystems due to the division of labor among species.
• Insurance Effect

  • Diversity is also believed to make species, populations, and ecosystems more resistant to environmental stresses.
• Development of Complex Collective Behaviors

  • Diversity could also favor the development of complex collective behaviors, including in organisms without a nervous system, as demonstrated by a certain species of bacteria.
• Density-independent limiting factor is when the population’s density does not directly affect in population.
• The density-dependent limiting factor are factors that affect population growth and population density.
• Exponential Growth: When a population reaches its carrying capacity, resources are plentiful for every organism, causing the population to grow faster and faster as it increases in size.
• Logistic Growth: When the population reaches its carrying capacity, the population starts to decrease.
• A limiting factor is a resource or environmental condition that controls or prevents the population from increasing.
• Infectious and deadly diseases, such as COVID-19, and parasites thrive and spread more rapidly in densely populated areas.
• What is found in the shark's head?

  Ampullae of Lorenzini
• The Ampullae of Lorenzini contains small pores with containers that are filled with conductor gel connected with nerve fibers
• The Lateral Line Sensory Organ is a series of small canals along the shark’s sides.
• The Lateral Line Sensory Organ contains tiny sensory hair-like structures sensitive to water movement.
