The answer is C. Just like other most other plants, plant-like protists have the chlorophyll pigment that harnesses sunlight to make their own energy. This is why they are categorized as autotrophs. Animal-like protists, on the other hand, are heterotrophs because they consume other organic molecules by engulfing hence categorized heterotrophs.
Answer:
When you chew, it is a sort of digestion, and it starts the whole process.
B. mutualistic symbionts.
C. herbivores.
D. parasitic symbionts.
In general, more complex animals are
A. More likely to rely on chemical digestion than to rely on mechanical digestion
B. more likely to perform intracellular digestion than extracellular digestion
C. more likely to have one body opening than to have two body openings
D. more likely to have a digestion tract than to have a gastrovascular cavity
Answer: 1. B. mutualistic symbionts.
Explanation:
A mutualistic symbiotic relationship is the one in which the two species lives in close association and both of the species obtains the benefit of living together.
Cattle depend on microorganisms in their digestive tract to digest the cellulose in their diets is the example of mutualistic symbiotic relationship. This is due to the fact that cellulose is a biomolecule which is obtain in leafy diets of the cattles. This is difficult to digest by the digestive system of the body of these cattles therefore, the function of digestion is performed by the microbes present in the digestive tract. Both of the organisms attains nourishment after this process.
Answer: 2. D. more likely to have a digestion tract than to have a gastrovascular cavity.
The complex animals are expected to have a complex digestive system. The gastrovascular cavity secretes digestive juices which aids in the process of digestion.
Answer:
c. limiting factor.
Explanation:
The limiting factors are environmental or ecological factors that act directly on the living beings of a population, limiting their size, since these factors determine their birth, mortality, migrations, etc. They are the ones that regulate the growth and expansion of a species.
If environmental factors are optimal for the development of a living being, they favor the growth of that organism in that biotope. But if any of these factors prevents the growth of a species, there is talk of a limiting factor.
Among these physical and chemical factors that determine the biotope include:
- Abiotic factors (do not depend on population density):
Climate:
Light. Only the most superficial organisms access it in water. On land, there is also competition in leafy areas to access it.
Temperature. Some living beings cannot live at the temperature that others live.
Water: It is necessary that it rains or that living beings can access water in order to live. If there is no water, they die.
Atmospheric pressure.
Non-climatic:
Soil factors: The chemical composition of the soil, its pH, salinity, etc. It makes some plant species may or may not survive in it.
Factors of the aquatic environment: The concentration of O2, dissolved CO2, the degree of salinity, the existence of currents, etc., limits the development of some organisms.
- Biotic factors (depend on population density):
Food. If they do not have enough food, the population will have to be smaller.
Interspecific relationships. The number of predators limits the number of prey, and vice versa.
Intraspecific relationships. The relationships established between individuals of the same species can also limit their existence.
