Because plants are producers - they make food from sunshine. They are eaten by herbivores which are then eaten by carnivores. Each time something is eaten the amount of energy in the resources it eats gets less until at the apex of the food chain there the available resources will only support a few individuals.
Most turbellarian species are indeed marine, but they exhibit a variety of ecological roles, including scavengers, predators, and even herbivores. While many are found in marine environments, some turbellarians inhabit freshwater and terrestrial ecosystems as well. Their feeding habits can vary widely depending on the species and their specific habitat. Overall, while scavenging is common among marine turbellarians, it does not encompass the full range of their ecological diversity.
Terrestrial
Yes, internal fertilization is a reproductive strategy used by virtually all terrestrial animals. In aquatic environments, external fertilization is much more common.

In chaparral ecosystems, common predators include coyotes, bobcats, and various raptor species such as hawks and owls. These animals are adapted to the dense shrubland and play crucial roles in controlling prey populations. Smaller predators like foxes and weasels may also inhabit these areas, utilizing the cover for hunting and nesting. Overall, the diversity of predators contributes to the ecological balance of chaparral habitats.
Some common predators of the western gray squirrel include birds of prey such as hawks and owls, as well as terrestrial predators like foxes, bobcats, and coyotes. Additionally, domestic cats and dogs may also pose a threat to western gray squirrels.

Marsupials face a variety of predators depending on their habitat and species. Common predators include birds of prey, such as eagles and hawks, as well as terrestrial carnivores like dingoes, foxes, and feral cats. Larger marsupials may also be threatened by humans through habitat destruction and hunting. In some regions, introduced species have significantly impacted marsupial populations by preying on them or competing for resources.
Peacocks, specifically the males known as peafowls, are preyed upon by a variety of predators in their natural habitats. Some common predators of peacocks include large birds of prey such as eagles and hawks, as well as terrestrial predators like big cats (such as leopards and tigers) and wild dogs. In addition, smaller predators like snakes and wild boars may also pose a threat to peafowls, especially their eggs and chicks. Peafowls rely on their keen eyesight and ability to fly short distances to evade these predators and protect themselves and their offspring.
In a rock pool, common predators include starfish, which feed on mollusks and small invertebrates, and crabs that hunt for smaller creatures like shrimp and snails. Sea anemones also act as predators, capturing prey with their tentacles. Additionally, some fish, like blennies and gobies, can be found in these environments, preying on smaller organisms. These predators play a crucial role in maintaining the ecological balance within the rock pool ecosystem.
Prawn predators are animals that hunt and consume prawns as part of their diet. Common prawn predators include various species of fish, such as cod and snapper, as well as birds like herons and egrets. Additionally, certain crustaceans, like larger shrimp and crabs, may also prey on prawns. These predators play a crucial role in maintaining the ecological balance within aquatic ecosystems.
