Species between which competitive relations are established in the ecosystem 1 spruce and birch 2 gray

Species between which competitive relations are established in the ecosystem 1 spruce and birch 2 gray and black rats 3 woodpeckers and sparrows 4 moose and wild boars.

In order for a competitive relationship to be established between two species in an ecosystem, these species must have similar interests. That is, they can eat the same food, inhabit the same area, and so on.

Let’s analyze each pair to identify competitors.

1. Spruce and birch. If we look at an ordinary forest, we will immediately notice that both spruce and birch trees grow there. Like all plants, they feed on nutrients from the soil and need sunlight. That is, on the face of all the reasons to compete: one territory, food with the same resources. Conclusion: this pair is competitors.

2. Gray and black rat. They live in the same conditions, their diet is the same. Conclusion: competitors.

3. Woodpeckers feed on insects they find in trees, and sparrows find food on the ground. They do not compete for space in the trees. Conclusion: not competitors.

4. Elks and wild boars. Wild boars feed on roots, berries and plant fruits. Elks eat shrubs and various plants. They also do not compete for territory. Conclusion: not competitors
