The answer to this question would be soft agar plate.
The semisolid medium tube is mostly used for containing the specimen. It is hard to examine semisolid medium since the bacteria can grow in the upper part, middle part or even the lower part of the medium. In agar plate, the bacteria always growth in the upper part so it is easier to count the bacteria.
But semisolid can give some more information in determining whether the bacteria is anaerobic by looking for bubble inside the medium. Anaerobic bacteria can do fermentation that will produce air.
Explanation:
En primer lugar, la biodiversidad y los ecosistemas nos brindan servicios esenciales para el bienestar humano. Nos otorga oxígeno, alimento, vestimenta y salud. Asimismo, son importantes para el desarrollo socioeconómico de la sociedad.
Answer:
Food webs illustrate how energy flows through ecosystems, including how efficiently organisms acquire and use it.
Autotrophs, producers in food webs, can be photosynthetic or chemosynthetic.
Photoautotrophs use light energy to synthesize their own food, while chemoautotrophs use inorganic molecules.
Chemoautotrophs are usually bacteria that live in ecosystems where sunlight is unavailable.
Heterotrophs cannot synthesize their own energy, but must obtain it from autotrophs or other heterotrophs; they act as consumers in food webs.
