Answer:
Chemical evolution is the formation of complex organic molecules from simpler inorganic molecules through chemical reactions in the oceans during the early history of the Earth.

Abiotic variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight. The boundaries of an individual abiotic factor can be just as unclear as the boundaries of an ecosystem.These are often referred to as abiotic factors. Abiotic factors are non-living elements found within an ecosystem. There are six abiotic factors that affect plant growth: air, water, space, temperature, light and soil (nutrients).The two most important abiotic factors affecting plant primary productivity in an ecosystem are temperature and moisture.
LEARNING OBJECTIVE[ edit ]
Identify the abiotic factors that affect plant growth
KEY POINTS[ edit ]
Primary production, on which almost all of life on earth is dependent, occurs through either photosynthesis or chemosynthesis.
Annual biomass production, used to estimate net primary productivity by plants in an area, is directly influenced by an environment's abiotic factors, which include temperature and moisture.
Warm and wet climates have the greatest amount of plant biomass because they offer conditions in which photosynthesis, plant growth, and the resulting net primary productivity are highest.
TERMS[ edit ]
biomass
the total mass of all living things within a specific area, habitat, etc.
eco-region
a region, smaller than an ecozone, that contains a distinct biodiversity of flora and fauna
chemosynthesis
the production of carbohydrates and other compounds using the oxidation of chemical nutrients as a source of energy rather than sunlight; it is limited to certain bacteria and fungi
Answer:
D- changing the dna of a crop plant to make it more susceptible to pest insects.
Explanation:
Genetically modified organism are those organisms in which the technology of genetic engineering is used to change their genetic makeup. Due to this change in genetic makeup allow the organisms to resist against disease causing microorganisms, pesticides and also increased the productivity of crops. In animals, genes are change to increase milk or meat production.
By releasing carbon dioxide into the air
