• Biotic factors refer to living things that affect the growth and survival of other living things such as animals,plants and microorganism
• Sexual Reproduction is a process that involves the union of gametes
• The gametes came from two parents with the opposite sexes
• Gametes are produced by a type of cell division called meiosis
• Meiosis in sperm cell division called spermatogenesis
• Meiosis in egg is called oogenesis
• Fertilization is the union of the male and female gamete
• External fertilization is a watery or moist
• Internal fertilization is the egg fertilized
• Asexual reproduction does not include the union of gamete
• Asexual is a method wherein an individual produces offspring’s
• Binary fission is the simplest form of asexual reproduction
• Bud formation or budding is common not only in plants
• Fragmentation involves the development of new organism
• Regeneration is the ability to replace any lost or missing part of the body
• Spore formation or sporulation involves the formation of many spores
• Vegetative propagation common in plants
• Abiotic factors are the non living components of the area
• Abiotic factors are group into three categories
• The three categories are the Climatic Factors, Edaphic Factors, and the Physiographic Factors
• Biotic factors are the living things comprise
• Climatic Factors are those that affect the weather of the place
• Edaphic Factor is the soil factor which includes the type of soil, texture, structure, depth, drainage, pH, nutrients, organic matter content, etc.
• Physiographic Factors are the physical features of an area such as elevation, landforms, water bodies, vegetations, etc.
• Ecosystem refers to all organisms (plants, animals, microbes) in a given area interacting with each other and their nonliving environment
• Food chain this is the series of eating and being eaten
• Food web this is interconnected food chain
• Herbivores are the plant eaters
• Carnivores are the flesh eaters
• Omnivores are the consumers
• Decomposers are the final consumers
• Detritivores are the macro decomposers
• True decomposers are the bacteria and fungi
• Topography (altitude and slopes) is the varied landscapes that exist
• Direction are pertains to where the area is facing
