Answer:

Animals are dependent for multiple reasons.

Explanation:

The energy is transferred to animals when they eat plants. They also need it because vitamin D is given when animals get sunlight on their bodies, building strong bones and healthy marrow. The same happens when they eat vitamin D-rich plants. Hope this is helpful!

Fish lay a large number of eggs, few of which are fertilized and very few of which hatch into young ones. Still fewer live to ma

vazorg [7]

The answer would be survival of the fittest.

This metaphor, "survival of the fittest," was used by Herbert Spencer to explain natural selection. It is sometimes also referred to as the survival for existence. This phrase came from the Dawinian theory of evolution where he explains that all species are capable of producing many offsprings. However, the survival of those offsprings depends on their ability to adapt to the risks and opportunities of the external environment.

This relates to your scenario in the sense that fish lay a lot of eggs in the beginning but not all of them would live to achieve maturity. This is because even as eggs, they have many predators and are exposed to other elements. The threat pushes on even if they are able to hatch and grow up.

Deciding between recycling of conventional plastics and developing biodegradable plastics is a complex issue because:___________

Julli [10]

Answer:

Conventional plastics-

"Plastics are typically organic polymers of high molecular mass, but they often contain other substances."

Composition-

"Oil-based polymers is currently used in packaging applications. These are virtually all non-biodegradable, and some are difficult to recycle or reuse due to being complex composites having varying levels of contamination.

Biodegradable plastics-

"They are largely manufactured from renewable natural resources, to produce biodegradable materials with similar functionality to that of oil-based polymers."

Explanation:

Complex Issue-

Diversity of biodegradable materials and their varying properties makes it difficult to make simple, generic assessments such as biodegradable products are all ‘good’ or petrochemical-based products are all ‘bad’.

Biodegradable packaging materials are most suitable for single-use disposable applications where the post-consumer waste can be locally composted.
