The hay included as part of the culture medium provided a food source for bacteria. Bacteria are a good food source for some typ

es of protists.

Answer:

  • Protozoans → would not have survived because they have no way to produce their own food → Heterotrophs
  • Algae → would have survived without this food source → Heterotrophs

Explanation:

The protist kingdom is composed of two main groups.  The principal difference between them is that algae can produce their own food, while protozoans need to ingest other organisms or organic molecules to survive.

  • Algaes are autotroph
  • Protozoans are heterotroph

<u>Protozoans</u>:

Microscopic unicellular organisms, eukaryotic and heterotrophs -predators or detritivores-. Most of them are aquatic free-living organisms, but some species are parasites. They feed on<u> bacteria</u>, other organic wastes, and other microscopic organisms. The phagocytosis process is normally used to ingest the food, invaginating their cell membrane.  

<u>Algae</u>:

Eukaryotic micro- or macroscopic organisms. Autotroph and photosynthetic. They might be either unicellular or pluricellular. They use sunlight to synthesize organic matter from water, CO₂, and mineral salts. Unicellular ones can be free-living or associate with others to form colonies. They are part of the phytoplankton and are ingested by heterotrophic organisms. Pluricellular algae do not create real tissues but they compose a tale. The depth at which they inhabit depends on the pigments they produce. All of them inhabit fresh or sea waters.

Oliga [24]
Unlike women, men do not experience a major, rapid (over several months) change in fertility as they age (like menopause). Instead, changes occur gradually during a process that some people call andropause. Aging changes in the male reproductive system occur primarily in the testes.

Where is the energy shown in the equation transferred as a result of photosynthesis?
Leto [7]

The right answer is into sugars.

Photosynthesis aims to create energy (in the form of carbohydrate) from the

light energy from the sun. The organisms that use the photosynthesis

mechanism are phototropic because they make organic materials from

inorganic materials.

Which of the following is not a function of the inflammatory response?A. Prevents the spread of the injurious agent to nearby ti
Misha Larkins [42]

Answer:

B. Replaces injured tissues with connective tissue

Explanation:

Inflammatory responses are natural defense mechanism of body of higher organisms which have been evolved to protect the organism from various types of infections and injuries. The main function of his response is to -

  1. Localize the injury so that it will not spread to the other parts of the body
  2. Eliminate the injurious agents to prevent further increase in the infection inside the body
  3. Remove the damaged tissue of the body so that it can start the mechanism of tissue healing

Thus, all the functions of the inflammatory responses that are mentioned in the options are correct except option B.

In your own words Describe how autotrophs and heterotrophs obtain energy. please this answer must be at least 150 words any one
blsea [12.9K]

The autotrophs are the primary producer in the food chain and they are the ones who initiate the food chain. They produce food by using sunlight or sometimes chemical energy or reactions. They primarily use carbon dioxide, sunlight and water to form sugars or carbohydrates which become their energy source. They use the process of photosynthesis or chemosynthesis to generate food. Examples of autotrophs are green plants, green algae, bacteria.

Heterotrophs cannot make their food via sunlight or other inorganic sources and hence are dependent on the autotrophs or other animals. The heterotrophs have been ranked as secondary and tertiary consumers and cannot be producers.  They consume the organic products made by autotrophs to obtain energy for various metabolic and biological activities. The heterotrophs can be herbivore, carnivore, fungi, parasitic plants.

Some are photo-hetrotrophs,  who use light as energy but cannot use carbon  dioxide as the carbon source since they cannot fix the carbon like autotrophs.
