Q.what is ecosystem
Q.what is environment
Q.what is exothermic reaction
Q.what is endothermic reaction
Answers
Answer:
Ans 1 - An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. ... Ecosystems can be very large or very small
Ans 2 -the circumstances, objects, or conditions by which one is surrounded. 2a : the complex of physical, chemical, and biotic factors (such as climate, soil, and living things) that act upon an organism or an ecological community and ultimately determine its form and survival.
Ans 3 - An exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative." Exothermic reactions usually release heat and entail the replacement of weak bonds with stronger ones. ... Most of the spectacular chemical reactions that are demonstrated in classrooms are exothermic and exergonic.
Ans 4 - Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products. ... Physical processes can be endothermic as well – Ice cubes absorb heat energy from their surroundings and melt to form liquid water (no chemical bonds are broken or formed)
Answer:
An ecosystem is a community of living and non-living things that work together – it consists of abiotic (soil, water, air) and biotic parts (flora, fauna). ... An ecosystem can be as large as a desert or as small as a tree. The major parts of an ecosystem are: water, water temperature, plants, animals, air, light and soil
The surroundings or conditions in which a person, animal, or plant lives or operates is called environment.
Exothermic reactions are reactions or processes that release energy, usually in the form of heat or light.
Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products.
