Life Science - 3rd Grade Science

Animals form groups to increase their chance of survival. The animals work together to hunt, raise their young, protect each other, and more. Survival would be much more difficult if some animals lived on their own rather than in a group.

Each organism is unique because they are all different. No two organisms are identical. Each offspring inherits characteristics from their parents, which gives them their make-up. Different organisms move through different life cycles, which put them at different stages. Many animals have different ways of caring for their young, gathering food, or life expectancies. Plants come in varieties of sizes, colors, and shapes. Each organism is unique.

The statement in the question is valid. Animals of the same species will have physical traits that are the same across all members. Giraffes all have long necks, cats have four legs, and birds lay eggs are just a few traits that do not change within a species. It can be assumed that all new giraffes born will have long necks because this is an inherited trait that is found across all giraffes.

Living in groups provides animals with many benefits. A large group of animals is less likely to be bothered by predators, there are more females to care for and protect the young, and more members to look for food sources. Working together provides them with more opportunities for survival than living alone does. Animals often fare better when living together than those outcasted to living alone.

The statement in the question is false. There are similarities between behavioral traits in animals of the same species. Honeybees can be expected to collect nectar and make honey, birds can be expected to build nests, and fish can be expected to swim. These are just a few examples of behaviors that are typically the same across a species.

Basic needs are things that people need to survive. In order to survive, people require food, water, shelter, and clothing. Though schooling is an important benefit to help people be successful, it is not needed for survival.

The answers choices provide various parts of a plant:

Roots keeps a plant in the ground and absorbs water and nutrients.

Stems provide support for plants and carry water and nutrients from the roots to the leaves.

Leaves are where the food is made in a plant.

Flowers are essential for seed creation.

The correct answer is roots.

Living in a large family benefits the meerkats because they can split up the work and have members of the family working together to keep the family safe and healthy. Rather than all of the work falling on a few animals, it can be split up amongst dozens. Living in large groups like this help with protection, food collection, and general survival.

Large herds of elephants can be seen moving across the plains of Africa with their babies in the middle of the group's lines as they travel. If predators attack them, the babies are usually targets because they are smaller and weaker. If the female elephants keep them hidden and guarded, they are protected. This technique is to help babies survive.

Fish form these "bait balls" to distract their predators and make it more difficult for them to be eaten. This technique is all about survival. Forming groups makes each fish safer than if they were swimming alone.

If the meerkats were forced to live alone rather than in family groups, they might die. If they are busy gathering food or digging tunnels, they may not see predators. It would be hard for a meerkat to do all of the jobs by itself.

All of the answer choices list a benefit to animals forming groups. When animals form groups for survival, they can help each other raise the young, hunt, keep watch, gather food, find shelter, and survive. Animals in groups have more eyes looking for predators or prey. They also have less work to do individually because they can share the workload. Animals in groups often survive better than if they lived alone.

Monkeys are very social and live in large groups with extended family. Monkeys help each other groom and use it as a chance to spend time with each other. Without a group to help the monkeys could not groom themselves properly. They rely on each other for help with their survival needs.

Fish form these "bait balls" to distract their predators and make it more difficult for them to be eaten. This technique is all about survival. Forming groups makes each fish safer than if they were swimming alone. If a fish is swimming alone, it stands out and is more likely to be chased and eaten. When the fish are in a group, their chances of being singled out and eaten are decreased, and many times the large gathering of fish scares the predators off completely.

The term organism refers to an individual plant or animal. An organism is a living thing. An organism can be as simple as a single-celled life form or as complex as a human. Each organism does have a unique life cycle or stages that it travels through from birth to death.

There are both similarities and differences between the life cycle of a duck and a human. Both humans and ducks are born, go through a juvenile stage, move into adulthood, and then have offspring of their own. There is a difference to the start of their life cycles though, humans have live births, and ducks hatch from an egg.

At first glance, a snake and butterfly don't seem to have a lot in common, but they do have some similarities. One example is that they both have an adult phase. The path to get to adulthood may be different for a snake and butterfly, but eventually, they both reach the final stage and become adults.
