Biotic and Abiotic Factors Flashcards
It is the interaction relationship among physical factors in the environment.
Abiotic Factors
It is the study of the interaction between living and non-living and the interaction with its surroundings.
Environmental Science
It is the interactive relationship among _________ in the community.
Biotic Factors
Examples of abiotic factors
Water, Sunlight, Soil, Oxygen
Examples of biotic factors
Plants, Animals, Microorganisms, all living things
An important ecological factor, It is an inorganic substance that plays an important role in the ecosystem.
Water
It brings about changes in the life forms of plants and animals. As aquatic plants and animals have different structures from terrestrial form.
Water
It is very irregularly distributed on the earth’s surface. It has an important bearing on the character of the organisms that live in various types of habitats.
Water
What are the different types of plants according to water requirements?
Thropophytes, Mesophytes, Xerophytes,
Hydrophytes, Halophytes
These plants can adapt to year after a year where seasonal changes bring mark change in the amount of available water from the soil.
Thropophytes
Most of our plants bearing flowers and fruits are classified as _______. They need a moderated supply of water for subsistence.
Mesophytes
Plants that can be tolerated where water supply is very scanty.
Xerophytes
These plants thrive in places where The amount of water is abundant: usually, water plants are called _______.
Hydrophytes
Plants thriving in a place where the water available contains much dissolved salts.
Halophytes
It is another important ecological factor On land.
Soil
Types of Soil
Loam, Clay, Silt, Sandy
It is good for agriculture and made up of particles of gravel sand and clay with the addition of organic a material called humus, with 1 in diameter.
Soil
Smallest inorganic particle of soil compared with silt and sand. It retains water before drying; it is sticky and not suitable for plant growth. Water moves very slowly. It is often damp and poorly drained, about 0.005 mm in diameter.
Clay
Made up of very fine particles of soil and clay, deposited as sediments. It is about 0.05 to 0.005 in diameter.
silt
Inorganic soil particles are larger than clay or silt. Plants do not grow well because water goes rapidly through the spaces between particles and dries quickly. Its size is about 1 mm to 0.05 in diameter.
Sandy
Light is an important physical factor. Without light, life on Earth would be impossible.
Sunlight
It is an important factor because of its effect on metabolism.
Environmental Temperature
(O2) is another important abiotic factor for many living organisms.
Oxygen
It is the relationship that includes mating, assistance, gorgeousness, and competition. Organisms belonging to the same species must compete with one another for space; food, and mates.
Intraspecific
It is that relationships are also biological factors of great importance. Different species must struggle with each other for space and food. Since many species use
other kinds of animals for food, each habitat includes predaceous animals.
Interspecific
It is non-living parts of ecosystem
Abiotic Factors
It is living things parts of ecosystem
