Relation to the Environment
The environment contains many organisms, and they are interlinked with each other. All organisms are depending upon one or more other organisms.This environment consists of physical and biological attributes. The environment in ecosystems includes both physical parameters and biotic attributes.
• The physical environment: The abiotic factors like temperature light, climate etc.
• The biotic environment: Genes, cells etc.
Change in any environmental factor affects the state of an entire ecosystem.
Water has lot of oxygen which induces the growth of aquatic plants and animals. The physiological and morphological adaptations of the aquatic plants help them to survive in water even in the changing environmental conditions.
For example, large cellular air spaces allow the gas transportation in the roots and stems of plants. The transportation of gases used in photosynthesis reaction and in respiration.
Microbes use oxygen during respiration in drained soil. Anaerobic soil microorganisms use nitrate, iron like organic compounds in aquatic environments.
Osmoregulation is the process which helps fish to survive in high levels of salt water. Gills of fish form electrochemical gradients which mediate salt extrusion in salt water and uptake in fresh water.
Gravitational forces affect many geophysical properties of the Earth. During the growth of plants, the allocation of biomass is subject to mechanical failure because of the influence of the gravitational forces on the position and structure of branches and leaves.
How do we humans tolerate the gravitational changes?
Our cardiovascular systems take the lead role here. Yes, the cardiovascular systems are adapted to face any physiological changes like gravitational forces. It varies for organisms based on the shape, height, etc..
The behaviour like running, flying and the living habitat like cold or hot climate also play a role on the adaptation to gravitational forces.
Correlation of Gravity & Pressure
Osmotic pressure and climatic pressure influence on the organisms’s activities like respiration, flying, eating etc.
At higher altitudes the increase and decrease of oxygen are the limiting factor for life. Water transportation trees dependent upon pressure.
Genes are present in the nucleus of the cells. It contains the hereditary materials. This hereditary material is inherited to next generation and if any mutation occurs because of sudden change in climate, disease, or anything that will end up with the change of genes. This change of genes can change the habit and characteristics of the organisms.
